Question

Let us assume that you pass the above sampled signal through analog lpf (low pass filter) just above 100 hz. Is there aliasing (distortion) in the reconstructed signal? Why? What happens if sampling is done at 200 hz instead of 100 hz. You may check it by computing fft.

Answer 1

the angle of hr is 200 c2
$200 - 6569 { \frac{ {x)}^{?} }{?} }^{2} \times \frac{?}{?}$
