A band limited communication channel is available which allows transmission of signals between 0 to 20 Hz (a band limited channel which has the lower frequency limit of 0 Hz is called a baseband channel). This channel is to be used for transmission of music and S/N ratio is 13 db. Our task is to find out the ratio of Channel capacity / Bandwidth (C/B)? Hint: First find the channel capacity and divide it with bandwidth Select one option: a. 4.38 b. 3.80 c. 20 d. 87.6
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.
