Beschreibung
Zusammenfassung:	A signal processor including a signal receiving circuit, a pre-processing circuit, a period acquisition circuit, and a decoding circuit is disclosed. The signal receiving circuit is configured to receive the input signal. The pre-processing circuit is coupled to the signal receiving circuit and is configured to generate a square wave signal according to the input signal. The period acquisition circuit is coupled to the pre-processing circuit and is configured to capture several signal periods of the square wave signal. The several signal periods include several signal period groups, and several signal period groups include at least two of the several signal periods which are adjacent to each other. The decoding circuit is coupled to the period acquisition circuit and is configured to process decoding according to a time length and number of times of the voltage value change of the several signal period groups to obtain a decoding result.
