Consider a single tone signal of frequency 3300 Hz. A PCM is generated with a sampling rate of 8000 sample/sec. the required output signal-to-quantizing noise ratio is 30 dB. 1) What the minimum number of uniform quantizing levels needed?. And what the minimum number of bits per sample needed? 2) Calculate minimum system bandwidth required
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.
