Companding process

WebThe expander expands the high amplitudes and compresses the low amplitudes. The whole process is called companding (COMpressing and exPANDING). Companding is widely used in public telephone systems. There are two distinct companding schemes. In Europe, A-law companding is used and in the United States, μ-law companding is used. WebCompanding is the process of compression and then expansion. With companded system, the higher amplitude analog signals are compressed (amplified less than lower amplitude …

WebThere are two compression algorithms commonly used, the μ-law and the A -law [ 6, 10 ]. We use a device called expander at the receiver with characteristics complementary to the compression. It is used so that the overall transmission is not distorted. The whole process (compression and expansion) is called companding [ 7 ]. WebCompanding can be used to increase the accuracy of such signals. This is the process of distorting the analogue signal in a controlled way before quantising takes place, by compressing its larger values at the source and then expanding them at the receiving end. There are two standards used: A-law in Europe, and µ-law in the USA.
