2- Weaver's SSB modulator is illustrated in Figure as m(t) = cos 27 fmt, where fm < W, demonstrate that by proper choice of fi and f2 the output is a SSB signal. By taking the input signal LPF BW=W m(t) SB 90° 90° signal LPF BW=W X)
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.
