DIGITAL COMMUNICATION Let 0 and o be zero-mean, uncorrelated, random variables, with variance o?. Given the following bodacious random process (t) = 0 cos wt + ¢ sin wt a) Find the autocorrelation function Rxx(t, t) b) Determine whether x(t) is wide sense stationary (WSS) c) Find the condition under which (t) would not be WSS. In all cases, state all assumptions made and show all your work.
Quantization and Resolution
Quantization is a methodology of carrying out signal modulation by the process of mapping input values from an infinitely long set of continuous values to a smaller set of finite values. Quantization forms the basic algorithm for lossy compression algorithms and represents a given analog signal into digital signals. In other words, these algorithms form the base of an analog-to-digital converter. Devices that process the algorithm of quantization are known as a quantizer. These devices aid in rounding off (approximation) the errors of an input function called the quantized value.
