A synchronous motor takes 25kW from 400V supply mains. The synchronous reactance of the motor is 4ohms. Calculate the power factor at which the motor would operate when the field excitation is so adjusted that the generated EMF is 500volts.
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.
