Abstract: The present invention relates to a method of determining an ASK signal and a device thereof and a wireless power transmission device using the same. According to the present invention, the method of determining an ASK signal includes: a first step of receiving a demodulation signal of a received ASK signal; a second step of measuring a pulse time in which pulses forming the demodulation signal are maintained; a third step of storing the measured pulse time; and a fourth step of determining information of a current pulse of the demodulation signal based on the pulse time of the current pulse and the pulse maintenance time of the previous pulse. According to the present invention, even if an ASK signal is distorted due to various factors such as a long distance between a transmitter and a receiver for the ASK signal or an obstacle between the transmitter and the receiver, the recognition rate of the ASK signal can be increased for smooth communication. In particular, in the case of a wireless power transmitter, even if an ASK signal transmitted from a wireless power receiver (smartphone ED) is distorted due to a long distance from the wireless power receiver or an obstacle, the present invention can be applied for smooth communication between the wireless power transmitter and the wireless power receiver.
