Q2] A digitizing system specifies 55 dB of dynamic range. Howmany bit rate required to satisfy the dynamic range specification? What is the signal-to- noise ratio for the system? What is (S/N)q for the system> Q3] A PCM system requires 72 dB of dynamic range. The input frequency is 10 KHz. determine the number of sample bits required to meet the dynamic range requirements and specify the minimum sample frequency to satisfy the Nyquist sampling frequency.
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.
