摘要： A signal correcting method and a signal correcting device. The signal correcting method includes sampling a signal to be corrected at different sampling times, and comparing a signal value at each of the sampling times in one signal period with a preset signal value corresponding to the sampling time. When the signal value at the sampling time is equal to the corresponding preset signal value, the signal value at the sampling time is kept unchanged. When the signal value at the sampling time is not equal to the corresponding preset signal value, the signal value at the sampling time is corrected to be the preset signal value corresponding to the sampling time.
