3. A sampling system can be set to adjust its sampling rate in 25 Hz steps. Considering the signal spectra plotted below, specify the minimum sampling rate setting for the signals: a) gi(1) b) g:(1) +g:(1) c) g(1) g:(1) d) gi(t) + g(t) -250N G₁00 0 250N f(Hz) GO f(Hz) -(1500+50N) 0 1500+50N -250N Gy + 0 250N
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.
