Interpolation filter
Sigma Delta Modulator
Data Format
The interpolation filter interpolates from f
Comb filter, and the basic building blocks of this filter is a comb part and an integrator part.
This part is a 3rd order Sigma Delta Modulator consisting of three differentiators (delta blocks),
three integrators (sigma blocks) and a one bit quantizer. The purpose of the integrators is to
shape the noise, so that the noise is reduces in the band of interest and increased at the higher
frequencies, where it can be filtered.
Input data is on two’s complement format.
