Abstract

A comb filter arrangement has an integrator that outputs an input value to a signal path. The signal path includes a delay stage for adjusting the input value using a delay factor, a decimator that converts the input value into a decimated output value using a non-integral factor, a differentiator that generates an intermediate output value from the input value, and an interpolation arrangement that receives the intermediate output value and generates a decimated sequence of the output value.
