The present invention relates to a method for determining an ASK signal and a device therefor, and a wireless power transmitter using same, the method for determining data of an ASK signal, according to the present invention, comprising: a first step for receiving a demodulated signal of an ASK signal that has been received; a second step for measuring a pulse time which is the time during which a pulse of the demodulated signal is held; a third step for storing the measured pulse time; and a fourth step for determining data of the current pulse on the basis of, in the demodulated signal, the pulse time of the current pulse and the pulse holding time of the immediately preceding pulse. According to the present invention, an effect is achieved whereby, even when an ASK signal is distorted for various reasons, such as when the distance between a transmitter and a receiver of the ASK signal is far, or when other obstacles are present between the transmitter and the receiver, communication may be smoothly performed by increasing the recognition rate of the ASK signal. In the case of the wireless power transmitter, even when an ASK signal transmitted from a wireless power receiver (smart phone ED) is distorted because the distance from the wireless power receiver is far, or because of obstacles, the present invention may be applied so that an effect is achieved of enabling smooth communication between the wireless power transmitter and receiver.

Method and apparatus for determining data of ASK signal, and wireless power transmitter using the same
A method and apparatus for determining an amplitude-shift keying (ASK) signal, and a wireless power transmitter using the same is provided. The method of determining data of the ASK signal includes receiving a demodulated signal of a received ASK signal, measuring a pulse time during which a pulse configuring the demodulated signal is held, storing the measured pulse time, and determining information on a current pulse based on a pulse time of the current pulse of the demodulated signal and a holding time of an immediately preceding pulse.
