Abstract: A new prefilter structure is presented. The frequency response of the prefilter structure is derived from the combination of two cosine functions. By cascading these prefilters with an appropriate equalizer, low complexity filters with high stopband attenuation can be achieved. The proposed prefilter leads to a significant saving in the number of arithmetic operations in the prefilter-equalizer cascade structure.
