A pulse width modulation (PWM) system uses a carrier frequency of 1 kHz and encodes 1s and 0s by varying the width of the pulses between two values, W1 and W2. If the width of the pulses is varied continuously, what is the maximum data rate (in bps) that the system can support? A. 500 bps B. 1,000 bps C. 2,000 bps D. 4,000 bps
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.
