Signals and Systems Lec-17: Fourier Series- 1

In this Lecture, concept of Fourier Series is explained. i.e what is Fourier series representation of a given periodic signal and how to Fourier coefficients.

I didn't find any better lecture other than this in the whole youtube.
Thank you, Sir.

[harshitgautam]

Amazzzing lecture...if you r preparing without any coaching.. this is 4 u...thnku sir

[geeta_ka_VANI]

THANKYOU SIR ..my signal system GATE preparation is totally depend on your lecture only and previous year paper so its my humble request you to keep uploading the lecture as soon as possible .its really helpful for me thankyou again sir

hai all at 43;30, at k =0, the value of ak is not zero, that will become 0/0 form...so using LH-rule, we will get a0 = 3/2..please make a note of it

[mainwhihoon]

THere's a mistake, at 43:40 while calculating a0, there's one k in denominator as well, which will lead to a 0 by 0 form and not 0 so please correct that.

sir actually till this lecture, I have noticed that may be the topic called eigen functions and their representation in evaluation of response of an LTI system is not explained..

[amanuellaike]

THANKS A LOT SIR have final exam this weekend ....hope i will get an "A" ...IT HELPED ME A LOT ...thanks again

[narasimhareddy]

Thanks sir, I think this lecture is useful for those who are preparing for engineering classes, it won't useful in gate exam because we need to solve problem with in 1 to 1 1/2 minutes, so try to find some shortcuts, to solve problem which is useful to students in the competitive examination

[selvinadarajan]

This video is very useful for me sir thank u...

[sambitpatra]

thank u very much sir..for ur work..
sir can u plz tell me..when ur going to start control system..??
sir plz start control system After signal system because it's common to EE and ECE hence both Branch students will be benefited..thank u sir

[amitpaswan]

Sir ak to zero aana chahiye because area of signal over single time period equal to zero

[suribabud]

thank you sir please upload EDC tutorial vedios, and once thank you sir for your great job

[sachinjaiswal]

sir, what is weighted sum
and k in e^jwkt may be integer only?

[michaelmurmu]

also sir what is the difference between the "t" and "T" ? i.e
"t" (in e^jkwt) and "T" ( in w=(2*p)/T )

[jenil]

At 43:49
While substitute the value of k=0 the value of ak=infinite bcoz in denominator k is there
Reply fast....!!

[kshrikant]

great stuff... i follow your lectures regularly...i have one request...can you use simple pens instead of sketchpens for the upcoming videos. or filter out the noise of the sketchpen.

[saiakashsamayamanthula]

If possible please upload pdf of these lectures..

[mudhunurijanani]

sir could u please solve the l hospital rule at 43.00

[vinayvenkatesh]

All Continuous Signals are Analog but not vice Versa

[mukulshah]

sir plzz uplode BASIC ELECTRICAL MACHINE Lectures ... Heartily E-thanks
