Exponential Fourier Series Example #3

In this video we compute the exponential Fourier (EFS) series of a fully rectified sine wave signal sin(t). This computation involves computing the EFS coefficients Dn by projecting the signal onto the the nth exponential basis signal.

I wish I could super-like this. I just threw my lecture notes away because I can pause, scrutinize, and take notes about what you're saying. Thanks for the clear explanation!

[reingblak]

Although, I don't speak English very well, I understood your explanation, amazing explanation... Thank you so much!

[sudiptosaha]

thanks sir for clearing my doubts. In most of the books it is given that the output of full wave rectifier contains only even harmonics but when I did the fourier analysis I found both even and odd harmonics. Thank you once again sir

[Frank-gvfs]

thank you so much for this, made a difficult concept and explained it in a really clear and concise manner

[sergerovichpavliche]

Bro roasted me at mathematical level, saying "just basic stuff"😂

[joatvictor]

An awesome explanation! It would be very nice if you added more exercises about Fourier series and transforms.

[moheywael]

please, is there a minus in time 5:00 in expression 1/2*pi ( because you have to take the minus as a common factor also means to multiply it to minus )

[StevenKarma]

Great explanation like always. I'm a bit confused when you say e^[ j pi (1-2n) ] = -1 for all n. Would someone please explain how that works out? Thank you.

my bro taught me a 1 hour class in 6 minutes

[rajivnarayan]

Thank you very much, I needed this for calculating the output from a smoothing circuit :)

The man, the myth, the legend of Euler. I have a craving for a honey butter chicken biscuit and captain crunch. Can't wait for Endgame to come out. Idk if Iron man will be able to stop Kylo Ren. Ehh, I'll just go to the beach for now, I heard octopuses are there.

0:12 Should not *x(t) = |sin(t)|*, the absolute value instead as *sin(3π/2) = -1* but what we need is 1?

[terrydouglasjayasuriya]

Thanks for the video. I have a query. Why is it always equal to -1, referring to transcript at time 4:32. Thanks.

[manikantachowdaryimmella]

Sir I have a doubt,
As W(omega)=2, then sinWt=sin2t but why did you represented the waveform as sint?

[BaikalLV]

Hey, thanks for the video! One remark dough, shouldn't the j be numerator after you write the alternative form of sin(t) ? I was checking in Wolfram by the way.

[KevR]

Hey Guys, what is the table that I can refer to for solving sin(t) * e^(-jnwo*t)? If it's not a fourier series table, what integral table am I looking for?

[gamehacker]

What will be x(t) if we take 1, 2 instead of Pi, 2Pi

[kaursingh]

SIR =LIMIT OF INTEGRATION IS FROM ZERO TO PYE = SO THE FOURIER TRANSFORM IS SAME WHETHER U HAVE ONE WAVE OR WHETHER U HAVE INFINITE WAVES ?= THANK U

[balaji]

sir does the value of e^(j*n*pi) and e^-(j*n*pi) is also -1

[kaursingh]

U ARE VERY GOOD - WHAT IS U R FIELD OF RESEARCH
