Abstract
Presented in this paper are decorrelating transformations(referred to as DECOR transformations) to reducethe power dissipation in digital filters. The transferfunction and/or the input is decorrelated such that fewerbits are required to represent the coefficients and inputs.Thus the size of the arithmetic units in the filter is reducedthereby reducing the power dissipation. The DECOR transformis suited for narrow-band filters because there is significantcorrelation between adjacent...Keywords
