The apparatus includes a conventional front-end receiver for receiving the data in both a reflected-impedance telemetry mode and an active telemetry mode, and it further includes a digital signal processor for efficiently processing data samples of the received telemetry data. Processing the received data in software allows for great processing flexibility, including a convenient reconfiguration to accommodate new modulation formats and data rates for implantable devices developed at a later time. | |
