Abstract
The invention relates to a decimation filter comprising a direct cascade arrangement of digital first order and second order integration and derivation stages (22, 23, 25, 27) and a decimation stage. The decimation filter structure of the invention comprises additional branches (28, 29, 30, 31) for shifting the location of the attenuation zeros of the decimation filter and thereby reducing the order M and the number of structural elements M of the required filter.
