Consider the periodic waveform shown in Fig Q16 where T = 0.02 seconds, 8 = 0.006 seconds, and the average power of the periodic waveform is 10 Watts. a) Sketch the double-sided power spectrum of f(t) in the frequency band -300Hz to +300Hz. b) Using the 90% definition of bandwidth, obtain the bandwidth of f(t). c) If f(t) is filtered by an ideal bandpass filter which is centered at 150 Hz and has a bandwidth of 110 Hz, obtain an expression for the signal at the output of the bandpass filter. Assume that the phase of the filter is zero at all frequencies.
