Abstract:
1. A method for processing a wireless frequency-shift-keying (FSK) signal for providing a signal for a hearing aid, including the steps of: receiving said FSK signal by an antenna, amplifying said FSK signal in a first amplifier stage, limiting the amplified FSK signal in a limiter stage, splitting the amplified, limited FSK signal into a plurality of signal branches, the number of branches being greater than the number of distinctly detectable phase angles to be received, detecting the phase of the FSK signal in each branch of the plurality of signal branches, wherein the detecting step in each branch includes the steps of: calculating a logical signal vector based on the detected phase of the FSK signal in each of the plurality of signal branches, summing the signal vectors of the plurality of signal branches, deriving information from the FSK signal based on the result of the summation, and presenting the derived information to the hearing aid.
