DEVICE AND METHOD FOR DECODING DATA FROM WIRELESS SIGNALS

An electronic device receives wireless signals encoded with data in an amplitude-shift keying format. The electronic device passes the wireless signals through a low-pass filter. The low-pass filter has a cutoff frequency between a first frequency associated with data values of a first type and a second frequency associated with data values of a second type. The low-pass filter has the effect of changing the wireless signal from the amplitude-shift keying format to an on-off keying format without losing the data. The electronic device decodes the data from the wireless signal in the on-off keying format.
