Bode Plots Explained
HTML-код
- Опубликовано: 25 авг 2023
- Bode plots are an essential but sometimes confusing tool for frequency domain analysis. In this video, we'll start with an intuitive look at Bode plots. Afterward, we'll dive deeper: constructing Bode plots analytically and from recorded data.

No other explanation on the entire internet can connect the dots as this amazing video does. Thank you from my heart.
How incredibly kind of you. Thank you! 🥰
Wow, this is probably the most well made video about bode plot ever. Even after studying control theory in undergrads we struggled to understand it intuitively. Your visuals are just amazing. Along with your ASMR voice (as opposed to cranky old professors shouting at you) this makes for a very pleasant watching experience.
I suspect (due to the wide time gaps between, and unusual high quality of your videos) that you might be a PhD student (= passion for knowledge + financial struggle). I would love to support this channel once i get a job, so that you don't become discouraged and stop making these videos, but that might take some time (2 years at least, gotta finish my masters first).
I didn't remember subscribing to this channel, but I've been reminded why.
Clicked here faster than a MOSFET switching.
I struggled to find a clever reply, but came up short
Me too, I felt like a treasure popped up.
Wow such a vivid and highly descriptive statement 🎉😂
One of the best video for Bode Plots explaining how it is different from frequency domain analysis.
Enjoyed your stuff. Welcome back. I never realized how horrible my professor was until I watched your videos.
Nice to hear that. Thanks for dropping by.
Very well explained. Any amount of appreciation for your work is only inadequate. Well done and thank you!❤
More than adequate and much appreciated. Thanks for dropping by Suresh.
THANK YOU! After watching dozens of videos about Bode Plots, this one CLICKED!
So glad to hear that! I typically try to make videos about things I originally found difficult to find clear information on, and then communicate what made them make sense to me. Pleased that it worked for you.
I have never clicked faster on a video, welcome back to RUclips :D
Thanks! Nice to have finally finished something. ^_^

No other video on the internet helped me explain bode plots as simple as this video did. I understood this so intuitively, Thank you so much!
Great to see you back.
For new content, I'm voting for any subject in the control / DSP world
Thank you!
This does tend to be an area I consistently enjoy. There are a lot of PID control videos but I'm still thinking about making a dedicated video on it.
You make Body Plots very very understandable for me. I searched lots of videos and finally, you saved me. Thank you so much. I appreciate your work a lot. Go ahead❤
This is easily the best explanation I've seen on the topic. Amazing video.
This summarized one semester of my system dynamics lecture... Amazing!
Edit: forgot to say it but welcome back! Really happy to see a new content!
Delighted to hear that! While I am concerned that it is a little fast and covers a little too much, I do love seeing the full picture.
Thank you! I am enjoying creating again. 😊
Super intuitive video! I'm in my second year of EE and this has been super helpful with fortifying my understanding of everything going on conceptually.
Brilliant video. Some of the highest signal to noise content on RUclips for sure
Wowww this is fr one of the best explanations I have seen of this. I wish you could also narrate the rest of my control systems course 😭
Great to have you back!
And great to have you stop by Malcolm! :)
I'm so happy you're back! Your videos are trully amazing
Well thanks Matheus! I have another video I'm working on, but they take forever!! 😅
Welcome back, missed the content that you provide
Thank you! More videos coming "soon" 😉
I've been taught this in the college but didn't get how we use them in real life. Thanks a lot ❤. Make more videos on signal processing 😊
You're welcome and will do 😉
this video has answered many questions I had in mind. thanks, it was truly helpful.
Just a quick note to make things clear for people that might wonder why 20log(Vout/Vin) isnt used here. When writing how much a voltage has been amplified the correct way of writing is: dB = 20log(Vout/Vin). By using the law that power is proportional to the square of either voltage or current , the 20log(Uout/Uin) relationship can be derived. So just change that in the Gain graphs and it will be correct!
Otherwise, awesome video!
Thank you so much for this excellent explanation and visualization!!
Missed your videos so badly. Thank you very much for another banger ma'am.
PS: I am extensively using your Lowpassfilter 2.0 for my projects💖
Happy to. Delighted to hear that you're finding the low pass 2.0 useful. I'm hoping to create more projects focused on filling gaps in available/easy-to-use libraries in the future.
Very well and fast explained. Thanks a lot.
Where the hell have you been? Welcome back!
Started a new career and moved. Finally settling into both. Nice to see you DJ ❤
Huge Thanks!, now I get to know how to interpret the bode plots.
Beautifully illustrated, makes things so much easier to understand, even though I don't get most of the equipment/formula 😁Thank you for the video.
I'm glad to hear that, and thank you for the feedback. There's certainly some details I didn't cover...this gives more of a sketch than a "how to" for those parts.
Thank you, very clear and straight to the point, signal processing is way easier to understand here!
So glad to hear that! I find traditional signal processing explanations to be challenging, so I enjoy creating materials for this area.
Eagerly waiting for your videos
One of the very few, if not the only video, that shows bode plot and real electronic parts together! And also well explained. The only thing i would like had to seen would be, how different states would behave, like small phase/gain margin, or all the other conditions, that should be avoided.
ur a fuckin genius, im taking a control systems class and im lost as hell, this helped a bit. thanks.
Much informative and useful madam😊
I wish u posted more :( Amazing Content
The best explanation ever...keep making such videos :)
Working on one now 😉
Beautifully explained ❤
Thank you so much! 😄
Awesome presentation ❤
amazing explanation!
what an amazing content..........superb
Great explanation! Thank you!
Glad to hear that! Thanks for stopping by! 😊
Make more videos on control systems, you are helping a lot
Beautiful plotting.
Amazing , I like your Videos
Super! No se como agradecerte este gran bidio :) thanks a lot!
You're welcome! I'm so glad you liked it. 😊
Nice ! great job. Bravo !
Thank you! 😁
God Damn! if only my prof. was like this back then!
Thank you I really like this video it helped me a lot! Could you make a video on frequency response and how to compute a system's and steady-state? And include for mechanical engineering examples such as a mass. spring, damper. Again thank you!
Very nice job. Merci beaucoup!
Thank you so much for stopping by!
Very good video, thank you!
Certainly. Thanks for stopping by!
Lifesaver! Thank you so much ❤
Glad to hear it helped! 😊
Best explanation which connects dots practically and theoretically. Do you have python and arduino codes where we can try this personally?
thx for video it is short but full of information
Thanks Nadir, I'm glad that you think so. I was trying to slow down a bit through the details, so hopefully it wasn't too fast.
جميع فيديوهاتك مميزة جدا . امل ان تستمري في عملك هذا
أنت لطيف جدا، شكرا لك! [جوجل المترجم]
Thank you!
You're welcome! 😊
This was so clear and concise!! Thank you so much for this video!!
Can you please make on PID controllers as well? From a practical perspective? Like how with adding a zero or removing a pole or Right half plane zero affect the overall system and to overcome those how we design a PID controller?
You're welcome and thank you for the suggestion! I would love to make a video on PID control design for various plant behaviors.
@@curiores111yes! Pid please 😊
I told that before, but after PID, would be really nice a LQR video with the quality of your explanation. Btw, i would certainly buy a coursera course from you folks! Cheers
Could you explain the math of DSP(digital signal process), thank you very much.
Interesting pronunciation; which I have never heard before.... From Wikipedia ""Bode" is often pronounced /ˈboʊdi/ BOH-dee, although the Dutch pronunciation is Bo-duh. (Dutch: [ˈboːdə]).".. I did a bit of research and found that although his colleagues at Bell pronounced his name Boh-dee, as you do, and that he never objected; that his faimily, and he, pronounced it the Dutch way. I'll just leave this here. :) Otherwise nice work.
Can I use bode plots to calculate the transfer function of a motor with no parameters? Like back emf. Sweeping the input of the motor and getting an output from the shaft sensor maybe?
Sure, you can sweep frequencies to get an estimate of the transfer function. If you have an encoder you can measure the output positions relative to the input voltage (if that's what you're after). There's plenty of subtlety to that time of parameter estimation, so that's well outside the scope of this video.
Is it possible to bring in Accelerated Data, Convert it to velocity, and Show position? I am trying to capture acceleration data ways. 1) Pulses every 30 feet for 500 feet for velocity 2.) Calculate Velocity from accelerated data and compare.
Using accelerometer data to compute position is pretty difficult. Even a single integral will have substantial errors, but a double integral is particularly bad. You need to mix it with something else to get anything reasonable in terms of estimating position. If you're talking about 500 feet maybe GPS?
Thank you
You're welcome 😊
"Could you please provide an explanation of 'poles' and 'zeros' in a practical context? I'm interested in understanding how these concepts are applied in real life."
@@mrprad7425 I love the idea! I'll mull on it. Thanks for the suggestion Mr Prad
@mrprad7425
Let me give a short explanation.
Poles:
Poles are points in the complex plane where the denominator of the Laplace transform expression becomes zero, causing the system's transfer function to become undefined or infinite. In terms of the physical interpretation, poles represent the natural frequencies or resonant frequencies of a system. They indicate the points at which the system's response can become unbounded or oscillatory. A pole's real part determines the exponential decay or growth rate of the response, while its imaginary part contributes to the frequency of oscillation.
Imagine a simple mass-spring-damper system. The poles of its Laplace transfer function correspond to the system's natural frequencies. If there is a pole with a positive real part, it indicates that the system response will grow over time, possibly resulting in instability. On the other hand, if there are poles with negative real parts, the system response will decay over time, indicating stability.
Zeros:
Zeros are points in the complex plane where the numerator of the Laplace transform expression becomes zero. Zeros represent the values of the input signal for which the output response becomes zero. In other words, they are the frequencies or inputs that the system can attenuate or cancel out. Zeros have a significant impact on the system's frequency response and transient behavior.
In the context of an electrical circuit, a zero might correspond to a point where a specific frequency of input voltage leads to no current flowing through a particular branch of the circuit. This could be due to a resonance effect or some other physical phenomenon that dampens the response at that frequency.
But better understand physically, you need to learn what's laplace transform conveying
airgapflux.in/search?q=laplace%20transform (these videos might help.)
s = sigma + j omega
s = exponential component + j oscillation/sinusoidal component

Where can i get the arduino and python code for doing the experiment.
Its code that I wrote. It's not been edited for third part consumption, however. I'll edit and post it when I have time.
So this is what glados does in her free time
APATURE SCIENCE WE DO WHAT WE MUST BECAUSE WE CAN
could you help me with my MSc project?
What kind of help are you looking for? Online, my help is pretty limited to some basic advice related to the videos. Difficult to offer much else.
