Question 2

What is the basic idea behind the fourier transform?

Answer 2

All waveforms are just the sum of sinusoids of different frequencies.

Question 3

What is the “Fourier Series”?

Answer 3

It is the fourier transform for periodic functions

Question 4

What is the mathematical definition for a periodic function?

Answer 4

If f(t) = f(t+T) where f is function, t is time, and T is period.
