Claim Text:
1. A signal correcting method, comprising steps of: sampling a signal to be corrected at different sampling times using a sampling module; storing values corresponding to the sampling times of a first period of the signal as a plurality of preset signal values; comparing, using a detecting module, a signal value at each of the sampling times in one signal period with a preset signal value corresponding to the sampling time, and when the signal value at the sampling time is equal to the corresponding preset signal value, keeping the signal value at the sampling time unchanged; and correcting, using a signal correcting device, the signal value at the sampling time to be the preset signal value corresponding to the sampling time, when the signal value at the sampling time is not equal to the corresponding preset signal value, wherein the step of comparing starts to be performed in the second period of the signal to be corrected.
