PROBLEM 4.1 Consider the circuit containing a nonlinear element N as showr in Figure 4.54. The v-i relation for N is given by: ia = c2v + cqVA + co for va > 0, and ia = 0 otherwise. ww R VI N VA Find the operating point values of the nonlinear element's voltage and current for vj = V1, where Vi is positive. Find the incremental change in ia (given by ia) for an incremental change in vi (given by vị).
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.
