An audio CD is created by sampling analog audio signals at a rate of 44.1 ksamples/s for each. Each sample is then encoded into a 16-bit word. What is the data rate of the resulting PCM signal? Determine also the size of data (in Mega bit unit) for 1 minute PCM signal.
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.
