A three-anode mercury-arc rectifier supplies a 250-kw 230-volt load and is energized from a 4,600-volt three-phase source through a three-phase transformer whose primaries are in delta. Assuming an arc drop of 20-volts, calculate: (a) the d-c load current; (b) the voltage and kilovolt-ampere rating of each transformer secondary; (c) the current and kilovolt-ampere rating of the three-phase transformer.
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.
