Tutorial Q1: Find the minimum sampling rate that can be used to obtain samples that completely specify the signals: (a) x(t) = 10cos(20nt)-5cos(100nt) +20cos(400лt) (b) y(t) = 2cos(20nt) + 4sin(20nt - π/4) +5cos(8t) Q2: Consider the analog signal x(t)=3cos2000xt+ 5sin6000rt+10cos12000πt (a) What is the Nyquist rate for this signal? (b)Assume now that we sample this signal using a sampling rate F, = 5000 samples/s. What is the discrete time signal obtained after sampling? Dr. Ahmed 10
