Q1. Binary data are transmitted through an AWGN channel with SNR = 5 dB and bandwidth of B Hz. Channel coding is used to ensure reliable communication. a) What is the maximum bit rate for data transmission in terms of channel bandwidth? b) If the bit rate is increased to 3B, how much the channel SNR must be to ensure reliable transmission of data?
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.
