Exponential Fourier Series:
Using the Exponential Fourier series, any periodic signal can be represented as a linear combination of the complex exponentials which are harmonically related to each other.

Waiting for this video thank you 😀👌🏻👌🏻👍🏻
Perfect explanation! Great job!
Very well explained
Very nice explanation
Im doing this right now nice timing
Thank you sir🎉
Why we use conjugate of the signal?
Hi there You frequently mentioned real signal! What is real signal?

The real signal is the one which doesn't contain any imaginary part. All the signals which we are seeing in our day to day life are the example of real signal.
1:45 What do you mean by complex signal vs real signal

Complex exponential e^(jwt) is the example of the complex signal. On the other end, all the signals which encounter in real life are real signals.

@@ALLABOUTELECTRONICS Thanks, when it's better to use one form over the other ?

According to the conviniency any of the form can be used. But exponential Fourier series is directly relatable to the Fourier Transform. But for academic purpose, Trigonometric is more easy for solving the examples. ( Particularly when there is a symmetry in the signal)
