Consider the voltage of a baseband signal varies over 13V. This signal is sampled nd quantized through a 3 bits-per-level quantizer. What is the quantization moise for the samples whose voltages: 0.6V, 1.6V, 2V.-0.05V and-5V? Solution: /= 3 bits per sample i.e., L = 8 levels in the quantizer. The maximum %3D
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.
