A Binary PAM employs rectangular pulses of duration To and amplitudes ±A to transmit digital data at rate of Rb = 105 bits/sec. If the power spectral density of the additive Gaussian noise is Nowhere No = 10-2W/Hz. The value of pulse Amplitude to achieve 2 probability of error 10-6 is
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.
