A six-pole three-phase wound-rotor motor is to be used as an induction frequency converter. The stator is connected to a 60-cycle source. At what speed, and in what direction, must the rotor be driven if it is to develop: (a) 120 cycles? (b) 100 cycles and 180 cycles? (c) 40 cycles?
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.
