A data acquisition system monitors the sounds created by bats in a cave which have an audio range of 10 Hz to 20 kHz. Assume that a pulse code modulation (PCM) system that represents each sample point by 8-bits is used to digitise the analogue sound emitted by the bats. If a (7,4) Hamming code is used to correct transmission errors, what is the minimum transmission bandwidth (data rate) required if binary phase-shift keying is used for signalling?
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.
