Multi-channel decoding systems capable of reducing noise and methods thereof

A multi-channel decoding method includes: receiving an input signal to generate a channel output signal; providing a first test signal serving as the input signal in a first calibration mode; and adjusting a DC voltage level of the channel output signal with a first calibration signal by reducing a...

Summary:A multi-channel decoding method includes: receiving an input signal to generate a channel output signal; providing a first test signal serving as the input signal in a first calibration mode; and adjusting a DC voltage level of the channel output signal with a first calibration signal by reducing a difference between a first predetermined reference signal level and a DC voltage level of the channel output signal generated from the first test signal.
