For a PAM transmission of a signal with =2kHz. Calculate the bandwidth if the sampling frequency is 5kHz and the pulse duration is 0.2Ts. If the transmission is changed to PPM or PWM, what will be the bandwidth with a rising time of 2% of the pulse width?
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.
