Companding is used in digital telephony systems, compressing before input to an analog-to-digital converter, and then expanding after a digital-to-analog converter. This is equivalent to using a non-linear ADC as in a T-carrier telephone system that implements A-law or μ-law companding. This method is also used … See more In telecommunication and signal processing, companding (occasionally called compansion) is a method of mitigating the detrimental effects of a channel with limited dynamic range.

WebMay 27, 2024 · Companding is used when you want a signal to noise ratio (SNR) that's largely independent of the signal level. Quantization noise is constant, so if the signal level varies, so does the SNR. Let's consider an … four phases of bone healingWebLet's assume 8 bits are used, so the number of quantization levels is 2^8 = 256. 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. four phases of careWebThe word Companding is a combination of Com pressing and Ex panding, which means that it does both.
