A dc-dc converter is built so that Vout(t) = q1Vin(t). The switch operates at 50 kHz with duty ratio of 50 %. This output voltage is applied to the input of a simple one-pole low-pass filter with a corner frequency at 500 Hz. What is the Fourier series of the signal at the filter output?

Q4 I need solution of part (b) and (c)

can you pls answer

1) From the plots, what is the frequency of the input signal (in samples as well as radians)? 2) From the plots, what is the frequency of the output signal (in samples and radians)? 3) What does echo do to the magnitude and phase spectra?
