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.
Probability of Error
This topic is widely taught in many undergraduate and postgraduate degree courses of:
Consider the concept for a base-band signal (see image below), where fH denotes highest frequency and fL denotes lowest frequency, what could be the minimum sampling frequency of a 4GHz carrier that is amplitude-modulated by a low-pass signal of maximum cut-off frequency of 1MHz if it is to be sampled ideally? Note: K value should be taken without any decimal value. Show your detailed solution for this problem.
