A signal is bandlimited to 4 KHz and a PCM is used to transmit it. The signal to quantization noise is atleast 40 dB and is normalised. What is the number of levels where the signal is encoded and what is the transmission's bandwidth
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.
