8. The CT signal x() = cos(5000xt) is applied to the input of the PCM system, and it is oversampled by 40%. The SNqR40 dB. Find the values of the following: i. The sampling frequency, ii. The quantization levels, and the bit rate of the PCM signal. -1 183
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.
