Abstract
A frequency sampling filter which has been implemented on a master digital hearing aid comprising a Texas TMS 320C30 DSP and associated circuitry is presented. The filter runs in real time and is used to provide a response, determined from the human audiogram, which compensates for loss of gain. The algorithm matches given requirements using a filter structure consisting of a comb filter having 400 zeros in cascade with 167 digital resonators.<>
