Abstract
This paper presents efficient modification of the
CICcosine decimation filter. The second order compensator
filter is introduced at low rate in order to
improve the passband of interest of the overall filter.
The coefficients of the compensator filter are
presented in a canonical signed digits (CSD) form,
and can be implemented using only adders and shifts.
Consequently, the resulting filter is a multiplierfree
filter and exhibits a high attenuation in the stopband,
as well as a low passband droop. |
