Q1: ph paper when required. A-The analog signal s(t) = 10 cos (20 pi't) cos (200 pi*t) is sampled at the rate of 250 samples per seconds. Determine the following: a- The maximum frequency component present in the analog signal. b-Nyquist rate. B- An analog signal having single frequency as 3 kHz is sampled with 5 kHz signal. Describe its frequency spectrum. What will be the output if the sampled signals are passed through a low-pass filter having cutoff frequency at 2.5 kHz?
