H.W: Thirty signals, twenty of them have 4kHz bandwidth, the other have bandwidth of 3 kHz are FDM/SSB multiplexed then modulated by an RF carrier of 800 kHz using AM modulator: 1- Calculate minimum multiplexing and transmission bandwidths. 2- Calculate multiplexing and transmission bandwidths if 0.7 kHz guard band is allowed between each two signals and below the first signal.
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.
