    摘要: A system and method for adaptive sigma-delta modulation. The system includes a input stage that produces a difference signal representing the difference between an analog input signal x(n) and a analog feedback signal z(n), the amplitude of the analog input signal x(n) within a first range [−a, +a]. An accumulator stage produces a accumulated signal that is a function of an accumulation of the difference signal, the accumulator stage transforming the accumulation of the difference signal so as to increase average magnitude while ensuring instantaneous magnitude does not exceed a predetermined value. A quantization stage produces a quantized digital signal y0(n) representing the accumulated signal. Based on the quantized digital signal y0(n), a adaptation stage produces a digital output signal z0(n), which is converted to the analog feedback signal z(n) by a digital-to-analog converter stage.

The cochlear implant system includes an electrode array in which each electrode is stimulated based on a stimulation sequence of pulses. The method includes deriving signal c(t) from an acoustic representative electrical signal, the signal c(t) including low frequency temporal information. An estimate of spectral energy e(t) is derived from the acoustic representative electrical signal, the signal e(t) including spectral information with substantially no pitch related temporal information. The stimulation sequence is created for at least one electrode in the array as a function of c(t) and e(t).
