Title: Control method for digital filter
Inventor: AKAGIRI KENZO
IPC: H03H17/04
Filed: 1990-01-31
Abstract: PURPOSE:To match each characteristic of plural digital filters corresponding to a critical band with a desired object level by calculating the effect of other digital filters in response to the characteristic of digital filter, excluding a prescribed offset from the result of each calculation for the correction and repeating the similar calculation. CONSTITUTION:The method adopts the so-called error feedback noise shaping processing in which quantization noise obtained by subtracting an input signal fed from a quantization output of a quantizer 62 to a quantizer 62 with an adder 63 is fed back to an adder 61 as a subtraction signal via a noise filter 64. Moreover, the filter coefficient of the noise filter 64 is determined for every critical band in response to the spectrum of an input signal. Thus, the influence of other digital filter is eliminated and the characteristic of each digital filter at a passing band corresponding to each critical band is matched with a desired object level.
