Plot the signal s(t) = cos(2pit), and then illustrate the resulting samples with the following sampling intervals: T_s= 0.5 sec. T_s= 0.75 sec T_s =1 sec. For each case, also sketch the reconstructed continuous time signal from the samples using linear interpolation (i.e. connecting samples by straight lines). In which case the sampled signal has aliasing distortion? What is the minimal sampling frequency and the corresponding sampling interval needed to avoid aliasing?
