Title: Harpal Mann - Innovator in Echo Cancellation Technology
Introduction
Harpal Mann is a prolific inventor based in Union City, CA, known for his significant contributions to the field of audio processing technology. With two patents to his name, Harpal has made strides in enhancing communication systems through innovative techniques.
Latest Patents
Among his notable inventions, Harpal's latest patents focus on "Echo cancellation using adaptive IIR and FIR filters." This method and system are designed to improve audio communication by receiving an input signal from a far end transmission while incorporating a near-end return signal. By injecting a corrective signal into the return signal before it is sent back, the system effectively reduces or cancels echoes. The first exemplary embodiment features the use of one or more adaptive infinite impulse response (IIR) filters and adaptive finite-impulse response (FIR) filters running in parallel, with outputs selected as the corrective signal based on filter performance evaluations. The second embodiment includes an adaptive FIR filter that chooses its output from either the adaptive IIR filters or a conditioned return signal, thus optimizing performance based on real-time determinations.
