complex periodic analog signal, consisting of frequency fi and its harmonics, is to be sampled. The signal is passed through a low-pass single-stage RC Butterworth filter rated -3 dB at 250 Hz. If signal amplitudes are considered negligible for M< 0.01, which the lowest sampling frequency that avoids aliasing?
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.
