Is a gain adjustable compression and expansion circuit in which one channel can be used for expansion and the other channel can be used for compression or expansion. The circuit contains small signal full wave rectification, the size of the test signal, which is used to adjust the gain of the input or feedback channel, the band gap precision reference source with good temperature characteristics, and the noise function.
