Question 2: Consider a continuous-time signal, x(t)= sin(480xt)-3sin(720xt), which is subject to analog-to-digital (A/D) conversion at a sampling rate of 600 samples per second to create a discrete-time signal, x(n). In this context, address the following aspects: a) Determine the Nyquist sampling rate required for x(t) to ensure accurate signal representation when subjected to A/D conversion, considering the signal's characteristics and bandwidth. b) Calculate the discrete-time signal, x(n), resulting from the A/D conversion. This involves understanding the effects of quantization, aliasing, and the implications of the chosen sampling rate on signal fidelity. c) If the discrete-time signal x(n) is subsequently passed through an ideal digital-to-analog (D/A) converter, analyze the reconstructed signal's characteristics and then determine the reconstructed signal.

subject to analog-to-digital (A/D) conversion at a sampling rate of 600 samples per second to
create a discrete-time signal, x(n). In this context, address the following aspects:
a) Determine the Nyquist sampling rate required for x(t) to ensure accurate signal
representation when subjected to A/D conversion, considering the signal's
characteristics and bandwidth.
b) Calculate the discrete-time signal, x(n), resulting from the A/D conversion. This
involves understanding the effects of quantization, aliasing, and the implications of
the chosen sampling rate on signal fidelity.
c) If the discrete-time signal x(n) is subsequently passed through an ideal
digital-to-analog (D/A) converter, analyze the reconstructed signal's characteristics
and then determine the reconstructed signal.
