Q26/ A Delta Modulation (DM) system is tested with a 10 KHz sinusoidal signal with al V peek to peek at the input. It sampled at 10 times the nyquist rate. Let m(t)=b* cos wmt. a) What is the step size required to prevent slop overload? b) What is the corresponding SNR?
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.
