Derive the expression for the discrete-time signal

(a) Derive the expression for the discrete-time signal .x(n) in Example 1.4.2 using the periodicity properties of sinusoidal functions.

(b) What is the analog signal we can obtain from x(n) if in the reconstruction process we assume that Fs = 10 kHz?

Example 1.4.2

Consider the analog signal

(a) Determine the minimum sampling rate required to avoid aliasing.

(b) Suppose that the signal is sampled at the rate Fs ≈ 200 Hz. What is the discrete-time signal obtained after sampling?

(c) Suppose that the signal is sampled at the rate Fs ≈ 75 Hz. What is the discretetime signal obtained after sampling?

(d) What is the frequency 0 s/2 of a sinusoid that yields samples identical to those obtained in part (c)?
