Q23/A Delta modulator is used to encode speech signal band-limited to 6 KHz with sampling frequency 400 KHz. For b=±1 volt peak signal voltage, find Minimum step size to avoid slope overloading. Let m(t)=b* cos wmt.
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.
