Abstract: A signal processing method and a signal processing system are provided. The signal processing method comprises the following steps. An original signal is provided. The original signal is gradually divided to be corresponding a plurality of stages. One high frequency signal and one low frequency signal whose frequency is lower than that of the high frequency signal are corresponding one of the stages. One of the low frequency signals corresponding to one of the stages is divided into another one of the high frequency signals and another one of the low frequency signals corresponding to the next one of the stages. An adjusting signal is obtained by filtering one of the low frequency signals out of another one of the low frequency signals.
