Q: A signal X(t) = Sin 4000 π t is convered to PCM with 256 quantizing levels. Calculate the bit rate of the resulting PCM signal. Assume that the signal is sampled at a rate 20 percent above the nyquist rate
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.
