QI: A PCM system is used to transmit base3 signal of 1024 level, the input signal works in the range between (20 to 60) MHz. Find the bit rate and signal to noise ratio in dB? Note that: the step size is considered to be half of system level.
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.
