Rudiments of Fourier Series Part II: Application on Real Signals using Python

1. Very brief mathematical foundation is demonstrated, but the viewers may jump that section with no big loss in understanding the idea.
2. Python program is presented to construct various time varying signals and to extract the frequency components composing those time-signals.
3. The program is explained to help viewers to write their own one.
4. Square waves generated from both the Python and LTspice are analysed using Python and the extracted frequency components were compared for illustrative purpose.
5. At the end, my voice from the last video, the "Rudiments of Fourier Series Part-I" is analysied and the components extracted using the Python are compared with those extracted using Audacity.
6. Further, a song from the movie "Silsila" sang by the Indian Nightingale, Lata Mangeshkar, is also analysied and illustrated the frequency components as well.
