Consider the analogue cosine signal y(t) = COS(8.8pit). It is sampled using a sampling interval of T = 0.5 sec.

What is meant by the term aliasing in regard to signal sampling?

What is the minimum sample rate that should be used to avoid aliasing?

Does aliasing occur in this case? What is the frequency of the reconstructed signal after low-pass filtering?

Plot on a graph the frequency spectrum of y(t). Plot on another graph the frequency spectrum of the sampled signal. Put the frequency values (Hz) on all frequency components shown on the graphs.
