In a binary pulse code modulation system, if the frequency of the baseband signal is 12.5 kHz, then what will be the minimum transmission bandwidth of the PCM waveform if a uniform quantizer having 32 levels is used.
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.
