Abstract
The digital delta-sigma modulator includes a signal input for receiving digital samples of N bits, and a digital filter connected to the signal input. The digital filter performs addition/subtraction and integration operations according to a redundant arithmetic coding for delivering digital filtered samples. A quantizer performs a nonexact quantization operation so as to deliver digital output samples of n bits, with n being less than N. The input of the quantizer is connected within the digital filter.
