1st diagram) Neither HWS nor QWS 2nd diagram) HWS &QWS follows From this lecture, all Fourier series concepts related to power electronics ( also signal and system) are easier for me... This graphical approach is best way to solve Fourier series than by integration..! Thank you sir ❤🙏
1. neither HWS nor QWS 2. both HWS and QWS. and thankyou sir for such an interesting tour of fourier series.. :) Sure loving this Power Electronics journey completely.. Bakreed Mubarak sir.. :)
Learning has become interesting with your lectures. Earlier Power Electronics was the subject I hated the most. But now it is the favorite subject. Thank you so much for the help. The answers are: 1. Neither HWS nor QWS 2. Both HWS and QWS
Just enjoyed thoroughly this lecture. Although was already knowing HWS and QWS, but u simplified it further. Now all fear for FS is gone. Thank you sir.
Sir, i have read fourier series in signals and systems ...but you made it more simple and understandable ...Now concept was more clear to me.. Thank you so much sir... and my answers are 1) it is not HWS & we know if any signal is not HWS , it should not QWS. so it is not QWS also 2) it is HWS & QWS
sir in quarter wave symmetry u said f(90+theta)=f(90-theta) and f(270+theta)=f(270-theta) sir.. but should we also include f(90+theta)=f(270-theta).. other wise your first home work can yield output as not HWS but is a QWS signal ?
Really...!! love this lecture, very easy way to draw waveform...till now I fear about the word SIGNAL and subject too, the reason is am from diploma background... now I am very interested to learn SIGNAL subject also, after this PE. by the way my answers are for 2nd A:: notHWS,QWS B::Both HWS,QWS.
sir i think the first one is quater wave symmetry but not half wave symmetry. it is quater wave symmetry because it satisfies the condition.If I am wrong the correct me. By the way your videos are nice...........
Sir, At 2:31 As already a0/2 is written, it is sufficient to write 1/Pi in integral(But u have modified it to 2*Pi). This is not required i hope.(Initially u have written correct only but later i think u forgot that a0/2 is there so, u have modified it.)
4:23 we can also write it as, (area of product of two functions) / (half time period)..... But why here half time period?? why not total time period?? Please please explain this. Aren't we actually finding avg of the resultant waveform in case of 'an' & 'bn', like we were finding in case of 'a0' ??????
property of definite integral is used (see the limits are changed .... previously from 0 to π but after applying property it became π to 0 and minus sign is got absorbed)

Correct...share with ur frnds too.
1. neither HWS nor QWS
2. both HWS and QWS.
and thankyou sir for such an interesting tour of fourier series.. :) Sure loving this Power Electronics journey completely..
Bakreed Mubarak sir.. :)
Most welcome..
SIR WHAT A VIDEO.....YOU MAKE US VISUALIZE THE BORING THEORY PORTION IN SUCH AN INTERESTING WAY.THANKS A LOT SIR.
Most welcome..share jarur krna..
I am Recommending these lectures for all of my friends.. These lectures are really awesome sir..
One of the most enlightening lectures I have heard
you have made the whole power electronics concept so easy to understand 👍👌
Learning has become interesting with your lectures. Earlier Power Electronics was the subject I hated the most. But now it is the favorite subject. Thank you so much for the help.
The answers are:
1. Neither HWS nor QWS
2. Both HWS and QWS
BEFORE LEARNING FROM GATEMATIC, I JUST LIKE MY BRANCH BUT, AFTER LEARNING FROM GATEMATIC I LOVE MY BRANCH .
Thank you very much sir.
Thank you sir, My doubt has been solved..
solution
Question 2
a) Its not a (HWS)
b)Its a (QWS) hence its (HWS also)
Just enjoyed thoroughly this lecture. Although was already knowing HWS and QWS, but u simplified it further. Now all fear for FS is gone. Thank you sir.
Sir, i have read fourier series in signals and systems ...but you made it more simple and understandable ...Now concept was more clear to me.. Thank you so much sir... and my answers are
1) it is not HWS & we know if any signal is not HWS , it should not QWS. so it is not QWS also
2) it is HWS & QWS
Correct explanation
GATEMATIC Education Thanks sir
Sir please upload Analog Electronics lectures . Your way of explaing is awesome.
Power electronic it is easy for you thank you very mutch
Wonderful concept sir
sir in quarter wave symmetry u said f(90+theta)=f(90-theta) and f(270+theta)=f(270-theta)
sir.. but should we also include f(90+theta)=f(270-theta).. other wise your first home work can yield output as not HWS but is a QWS signal ?
Thankyou sir!! For making us better in power electronics
amazing explanation of Fourier series with graph
Amazing and unique explaination
Really...!! love this lecture, very easy way to draw waveform...till now I fear about the word SIGNAL and subject too, the reason is am from diploma background... now I am very interested to learn SIGNAL subject also, after this PE.
by the way my answers are for 2nd A:: notHWS,QWS
B::Both HWS,QWS.
Thanks for awasome content
Q2
(a) nighter hws nor fws
(b) both means hws as well as fws
thank you sir it make me clear understanding about Fourier series
sir i think the first one is quater wave symmetry but not half wave symmetry. it is quater wave symmetry because it satisfies the condition.If I am wrong the correct me. By the way your videos are nice...........
Jakkaass video sirji
God bless uh with his best 🤗🙏👍👌🏼
Very useful information
2.a)not HWS and b) hws and qws both... Very nicely explained sir...
after all great work sir
Great Lecture! For example to say how great it is, go to 17:11 ...thank me later ;)
Sir your explanation is very simple and easy to understand. Kindly upload the lectures on signal and system , DSP.
2.
a) NOT HWS, NOT QWS
b) yes, HWS and QWS Both.
After this lecture....
#Mind = #Blown.
Thank you
Sir, At 2:31 As already a0/2 is written, it is sufficient to write 1/Pi in integral(But u have modified it to 2*Pi). This is not required i hope.(Initially u have written correct only but later i think u forgot that a0/2 is there so, u have modified it.)
superb sir..........nice lecture
thank you sir
Thank you! Nice lecture!
Thank you very much Sir! We understood.
a) Neither HWS nor QWS
b) both HWS as well as QWS
Thanks sir
Correct...enjoying or not..
Very much sir...
Thank You Very Much Sir.
Thank you sir for your effort..!
dear sir why are you putting 2/2*pi in every equation inspite of 1/Pi directly?
Sir please discuss the answers of questions of inverter part..because we don't have any idea how it asks in GATE please make a video of this..
You just tell the question nd don't discuss it's answer..otherwise your teaching is good
Good job sir....
simple and smart
hi sir, 1. neither half wave nor quarter wave symmetry
2. both half wave and quarter wave symmetry
crystal clear
awesome sir
integration of sin(x) = -cos(x), NOT +cos(x) => bn = -(2*Vdc/(pi*n))*(1-cos(n*pi))
Thank you so much sir.....
thank you very much sir
A-neither hws and nor qws
B-hws and qws both
nice lecture
thanku sir 🙏🙏
pls cover full gate syllabus of power etc. upto DC drive
Sir why Ao/2 here? In rectifier the dc value was only Ao
4:23 we can also write it as, (area of product of two functions) / (half time period)..... But why here half time period?? why not total time period?? Please please explain this. Aren't we actually finding avg of the resultant waveform in case of 'an' & 'bn', like we were finding in case of 'a0' ??????
Thank you sir ji
Why shouldn't we multiply by 4 and integrate with 0 to 90° in (odd +HWS function ) the graph is symmetrical from 0 to 90° and other parts. ?
Answer to Qs2 in the end:
a) Neither QWS nor HWS
b) Both QWS as well as HWS
Sir for multilevel inverter how to calculate thd
nice video
2a is HWS
2b is HWS AND QWS
2.) Both hws qws
A.Neither HWS nor QWS
B. Both HWS &QWS
None
Both
Thank u sir
THANKU SIR
2(a)no and (b)yes
What tools do you use sir??
Sir If we calculate An for half wave and qurater symmetry by your formula then. It not equal to zero please reply sir i calculate many times
You apply An =0 by consider graph but if we calculate An by your formula then it is not equal to zero
You calculate An=0 by consider graph but if we calculate An by your formula then it is not equal to zero
Q2.a)Neither HWS nor the QWS
Q.2b)Both HWS and qws
2 (A) neither HWS nor QWS
2(B) both HWS and QWS
At 27:38 i am not understanding... How (90+theta) and (90-theta) are have equal waveforms...
Help me please Anyone. ?
Bhai!! just observe carefully or put MIRROR on paper after drawing that waveform ok..or learn MIRROR IMAGES in Reasoning part
1.) Not hws and qws
Sorry. Integration of sine is - cosine. Why there is no minus sign?
property of definite integral is used (see the limits are changed .... previously from 0 to π but after applying property it became π to 0 and minus sign is got absorbed)
a) function is not HWS or not QWS
b) function is HWS or QWS
2a)not hws and not qws
b)both qws and hws
a) QWS , HWS
b) QWS, HWS
sir i m confused in (a) i m not sure about my ans plzzz correct me
a) is nothing
b) is both
2.a. neither HWS nor QWS
b. HWS and QWS
Raviteja Gindam can you Explain how 2(a) is not qws
a) it's not HWS
b) Yes it's QWS
1. not HWS
2. HWS & QWS
1. NOT HWS & QWS 2. HWS & QWS
not a HWS and QWS
both HWS and QWS
a- not Hws b- Qws, Hws
2a not HWS
2b HWS so qWS
stop praising your self again and again it decreases your fame. sir
Thanks so much sir
nice video
