DIGITAL COMMUNICATION Q1/ If the bandwidth of PAM system not exceed 4kHz is used to transmit voice signal sampled at Nyquist frequency. Calculate the bandwidth required to transmit the same signal using PPM system with rise time of 2% of pulse duration.
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.
