A method for use in an active implantable medical device (AIMD) including an external module and an implantable module having a stimulation transducer implantable in an implantee and configured to deliver stimulation energy to auditory tissue so as to cause a hearing percept, the method including: receiving, at the implantable module, from the external module via a transcutaneous RF link, an analog frequency-modulated RF signal (analog FM) including stimulation signals representative of sound； performing frequency-to-digital conversion upon the frequency-modulated signal to obtain pulse-formatted signals corresponding to the stimulation signals； and energizing the stimulation transducer based upon the pulse-formatted signals to cause the hearing percept.
