A signal x(t)=sinc(200*pi*t) is sampled (multiplied) by a periodic pulse train. Find and sketch the spectrum of the sampled signal. Explain whether you will be able to reconstruct x(t) from these samples. Find the filter output if the sampled signal is passed through an ideal lowpass filter of bandwidth 100 Hz and unit gain.
What is the filter output if its bandwidth B Hz is between 100 and 150 Hz?
What happens if the bandwidth exceeds 150 Hz?
