Abstract
Disclosed is a filter circuit, comprising a signal to be filtered, a difference circuit coupled to the signal to be filtered, a filter having an input coupled to the difference circuit, an integrator (or accumulator) having a first input coupled to an output of the filter circuit, and having a second input, and an accumulator coupled to an output of the integrator. A method of filtering is described also.
