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:
In the circuit based on direction of current shown, the current supplied by the current source I1 and current IR1 are entering the node A and current IIR3 is leaving the node A.
To calculate the current supplied by current source I1, apply KCL at node A by equating sum current entering the node to current leaving the node:
