ABSTRACT:
A non-integer CIC interpolation filter is provided for use in sigma-delta digital-to-analog systems, which realizes non-integer interpolation but eliminates the need for coupling of the integrators in the output domain. The present non-integer interpolation filter provides for more attenuation to all of the aliases of the input signal and has eliminated the need of complex computations.
