Thank you sir your explanation is very clear
Thank you
Thank you.
Finally, a worthy video❤
Really helpful
greetings from Istanbul, thank you for your clear explanation
Hlo But,how did you do this 😎
Hello, thank you for sharing your lectures! What whiteboard software do you use? Disappearing red pencil is very helpful function. I would like to use it in my recordings.
I use Notability for iPad. Good luck!
Hi, thanks for the video. How can i contact u directly for further enquiries?
How is it 34.9? Shouldn't the answer be 10.5 kbps?
Remember to use log_2 (log to the base 2) not log_10 :-)
If T1&T2 values obtained as 3 and 4 then it's fundamental frequency becomes T1/T2=3/4 means f=4/3 is it correct
No, Its Fundamental time period is 12 ( LCM of 3 and 4)
Yes sir if T1and T2 values are 3&4 then how to find frequency
Look for the lowest common multiple of T1 and T2, in your case 12.
Thank you so much Prof.Waleed, I have a question related to how much is the value receiver sensitivity at mobile end-user regarding this standard Wi-Fi (IEEE 802.11 n)?
Very nicely explained .. thank u it's helped me a lot to understand ❤
hi, how can I contact you?
Hi there, what's up?
I am a student and a freelancer, and I watch your videos for my studies. I really love your method of teaching. I was checking your channel, and I found some areas of improvement . If that got improved, your channel will grow faster. I just want to reach out to you and discuss the strategies for your channel. How can I contact you? Thanks
Thank you 😊
Wow is this a final year project for students?
It was a 4 week project for a group of year 2 students
The impulse response of a discrete-time system is the system's output when the input is a unit step sequence. True False
What you describe is the discrete step response, not the impulse response.
Select all the correct answers. The output of a first order system is y(t) = e^-4t The time constant of the system is 4 sec. The time constant of the system is 0.368 sec. ✔After two time constant the output of the system would have decayed to 13.53% of its initial value. ✔The time constant of the system is 0.25 sec. ☐ After two time constants the output would have decayed by 13.53%.
The transfer function of the system described by 2x"+x'-x=5u'+u is
Consider an at rest linear system described by y"+25y=2sint+5cos 5t The response of this system will be Decaying oscillations in time. Oscillatory in time. Growing oscillations in time: None of the above.
Thank you
where did you go to college
stupid college
your math has flaws
Sure. Tell me about it and I'll fix it.
i need to talk
Sure. What's the issue?
Professor, I am studying FM modulation and wondering if you could help me to solve this question: "Considering that the modulating signal band of a Brazilian commercial FM radio is 15 kHz, calculate, using Carson's Rule, the modulation index used by this radio". Kind regards!
You need 2 bits of information to find the modulation index: any 2 of: message bandwidth, bandpass FM bandwidth, frequency deviation. In this question you're only give the message bandwidth, so it looks like you need more information.
croissant
it's pretty straightforward
Thank you for this explanations. So what happens if m is between 0 and 1?
many thanks prof :)
how is that equal to 0.2
There's a typo in the penultimate step: the 5 should be a 3, but the final value is 1/5 = 0.2
Thanks!
What if x(t) given is equal to 1?

Hi Dr. Waleed, this video has no sounds
amazing explanation !
Was asked to take minutes of meeting yesterday I wish I had started here😢 Can you send the agenda via email a day before to the people attending the meeting or it should be presented only when at meeting
It’s expected that the secretary circulates the agenda ahead of the meeting, so people can come prepared
السلام عليكم ورحمة الله وبركاته عندي كم سؤال انفيرس فوريرير ترانسفورم ممكن تحلها عندي امتحان ماستر
No one explains Fourier Transforms as simply as you, thank you !
thank youuuuu
ليش 2pi
شكراً دكتور
Great
Great video, thank you for making it
Thank you for your help.
Hey i wanted to thank you so much for this video and the one about the diract delta function. My god I’ve been struggling trying to understand why or how they were getting these different answers and now it makes sense. I finally went back to grad school and it’s been 6 years since I did undergrad so I’m so rusty and forgot about many calc rules and sifting property etc. You’re amazing thank you 🙏
Thank you for this feedback - I’m so glad you found this helpful!
Great explanation sir. Thank you.
Thank you so much for the feedback!
Excellent explanation sir.
this video is pure gold, im a science material student
how would you convert the output y(t) to a laplace form Y(s)?
Either us a table of Laplace Transforms or carry our the Laplace Transform integral
