Let x(t)= Acos(27-20000t) and p(t)= pulse train of frequency 200 kHz, duty cycle = 0.25, in the switching modulator shown below. (a) Print out v₂ (t) and v. (t) in the time domain. (b) Find and plot the spectrums of v₂ (t) and v(t). 1 Repeat part 1 when x(t) is a periodic rectangular pulse train with duty cycle frequency of 5Khz. 4 at a Let x(t)= Acos(27-20000t) and p(t)= pulse train of frequency 200 kHz, duty cycle = 0.25, in the switching modulator shown below.
