A digital communication link carries binary-coded words representing samples of an input signal: ??(?) = 3 cos 600?? + 2 cos 1800?? The link is operated at 10,000 bits/s and each input sample is quantized into 1024 different voltage levels. 1. What are the sampling frequency and the folding frequency? 2. What is the Nyquist rate for the signal ??(?)? 3. What are the frequencies in the resulting discrete-time signal ?(?)? 4. What is the resolution ∆?

An analog signal is to be coded by an ADC. The signal contains significant frequencies up to 3.2kHz. If the system is operated at a bit rate of 36,000 bits per second (bps), answer the following: a) To avoid aliasing, the sampling frequency must be greater than or equal to kHz b) If the signal is sampled at the Nyquist rate, what is the Nyquist frequency? kHz h c) If the signal is sampled at the Nyquist rate, the number of bits per sample is number of quantization levels is and the Note: *When you use the formula bFs L in finding b, the result must be rounded up to the nearest integer.

What is a minimum number of sampling frequency required to have distortion free reconstruction of a digital signal from its samples?
