WebRead the article below, or scroll down to watch the Whiteboard Video. Companding is a process that happens in all analogue wireless systems to accommodate the limited dynamic range of FM radio. The process takes its name from the compression and expansion process that occurs to achieve a full dynamic range signal on output. WebThe logarithmic quantization is mainly used with linear systems with infinite quantization levels, while the zoom strategy is a beneficial control policy when uniform quantization is applied. It has two steps: “zoom-in” and “zoom-out” [17].

Thus, delta = 1.2/256 = 0.0046875 volts. To minimize the quantization error, we want to maximize the input signal range. The pre-amplifier should amplify the signal by a factor of 1/delta to maximize the input signal range. So, a1 = 1/delta = 213.333, and a2 = -1.2.
