Abstract

A digital parallelized Infinite Impulse Response (IIR) integrator filter comprising a first channel having a first input and second channel having a second input, a first adder to add the two channel inputs, an integrator to integrate the added channel inputs to provide a first channel output is described herein. The second input channel is adjacent in time to the first channel input. The second channel further comprises a second adder which adds the first output with the second channel input in order to produce a second output, adjacent in time with the first output. This configuration can be generalized to n inputs and m outputs.
