A delta modulation (DM) system is tested with 10KHZ sinusoidal signal, 10Vp-p. At the input, the signal is sampled 10 times the Nyquist rate. a) Draw sampled signals for 50 micro second duration time b) Draw the PAM for the sampled signal in (a) to get BW fs/2 %3D c) Draw the pulse width modulation for PAM in (b)
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.
