Fourier Series Frequency-Domain System Response Example #1
This video shows how frequency-domain concepts can be used to find the output signal of an ideal-low pass filter (LPF).
The input to the LPF is a periodic pulse train signal. We use the Fourier series representation of the input signal to determine which frequency components pass through the LPF to easily write a time-domain expression for the output signal y(t).
