摘要： Systems, devices, and methods are provided to inhibit apparent amplitude modulation in non-linear processing that causes distortion in a processed signal. One aspect of the invention includes a hearing aid. The hearing aid includes a microphone to receive an input signal, a speaker to reproduce the input signal, and a processor. The processor processes the input signal using a gain. The processor includes an inhibitor, which inhibits distortions, and an adjuster, which adjusts the gain. The inhibitor acts to smooth an envelope of the input signal to inhibit undesired modulation. The adjuster adjusts the gain if the envelope is either above or below a threshold.

摘要： A low power analog-to-digital channel includes a decimation filter coupled to a sigma-delta modulator. Various embodiments include a decimation filter including an output and a sigma-delta modulator coupled to the output of the decimation filter, where a clock frequency applied to the decimation filter is approximately a integral multiple of a sampling frequency of the sigma delta modulator. In an embodiment, the sigma-delta modulator includes one or more successive approximation converters. In an embodiment, the sigma delta modulator includes one or more area efficient integrators.
