Abstract
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.
Claims14
A multi-channel decoding system, comprising:
- a decoding circuit, for receiving an input signal to generate a channel output signal;
- a test signal generating circuit, for providing a first test signal serving as the input signal in a first calibration mode;
- and
- a calibration circuit, for adjusting a DC voltage level of the channel output signal outputted by the decoding circuit 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.
