Abstract
A frequency-shift-keying (FSK) transceiver for use in a hearing aid system and having a resonant circuit including a transceiver inductance (L), the resonant circuit having a resonance frequency, and a transfer function where gain and phase are frequency dependent, wherein the transceiver includes an FSK modulator receiving a data stream, and in response thereto outputting an FSK modulated signal to the resonant circuit for wireless transmission. The transceiver includes a controller monitoring the data stream received by the FSK modulator, and a phase equalizer unit controlled by the controller for substantially equalizing the phase distortion introduced by the frequency dependent resonant circuit. The invention also provides a hearing aid and a method of operating an FSK transceiver.
