(a) Consider an analog signal.

An analog signal is sampled at F_{s }= 600 Hz

**Nyquist sampling rate:**

The minimum rate at which a signal can be sampled without introducing errors, which is twice the highest or maximum frequency present in the signal.

It is observed that contains two frequency components. Compare the signal with the standard signal, . That are,

And,

From the concept of sampling theorem, the maximum frequency component is, f_{2}. Now calculate the Nyquist sampling rate.

Thus, the Nyquist sampling rate for is, .
