Abstract
A system and a method for demodulating a frequency shift keying signal are provided. The system includes a power transmitter and a power receiver. The power transmitter generates a frequency shift keying signal including a power signal and a power modulation instruction message. The power receiver detects a non-modulation period of the power signal within a waiting time, and then modulates a frequency of the power signal according to the power modulation instruction message to generate a pulse width modulated signal. The power receiver then calculates a full period of the pulse width modulated signal and then subtracts the non-modulation period from the full period of the pulse width modulated signal to obtain an undemodulated signal.
