Question

A digital communication link carries binary-coded words representing samples of an input signal

xₐ(t) = 3cos 600t + 2 cos 1800 t

The link is operated at 10,000 bits/s and each input sample is quantized into 1024 different voltage levels.
(a) What are the sampling frequency and the folding frequency?

Answer 1

The sampling frequency is 3600 Hz and the folding frequency is 1800 Hz.

Step-by-step explanation:

The sampling frequency, also known as the Nyquist frequency, is calculated by doubling the maximum frequency in the input signal. In this case, the maximum frequency is 1800 Hz, so the sampling frequency would be 3600 Hz.

The folding frequency, also known as the Nyquist frequency, is half of the sampling frequency. So in this case, the folding frequency would be 1800 Hz.
