Can you do FFT in Python?
In Python, there are very mature FFT functions both in numpy and scipy. In this section, we will take a look of both packages and see how we can easily use them in our work. Let's first generate the signal as before.
What is Fourier series in simple terms?
A Fourier series is an expansion of a periodic function. in terms of an infinite sum of sines and cosines. Fourier series make use of the orthogonality relationships of the sine and cosine functions.
What is the use of Fourier series?
Fourier series is just a means to represent a periodic signal as an infinite sum of sine wave components. A periodic signal is just a signal that repeats its pattern at some period. The primary reason that we use Fourier series is that we can better analyze a signal in another domain rather in the original domain.
