Abstract
Disclosed herein is a feedback reduction system for used in a hearing prosthesis. The hearing prosthesis will receive an input signal, process the input signal, and create a transformed output. However, the hearing prosthesis may suffer from feedback. Thus, a system to minimize the feedback in a hearing prosthesis may be desirable. One system to minimize the feedback includes down-sample circuitry configured to down-sample a first signal, creating a down-sampled signal. They system also includes a filter circuit. The filter circuit filters both the first signal and the down-sampled signal. The filter will output a filtered signal and a filtered down-sampled signal, respectively. Additionally, the system features up-sample circuitry that up-samples the filtered down-sampled signal. The output of the up-sample circuitry is an up-sampled signal. Further, the system features combining circuitry that creates a feedback-reduced signal based on the up-sampled signal, the filtered signal, and an input signal.
