Abstract
The input signal is filtered using at least two filtering operations (i.e. at least two types of transfer functions), and then is reconstituted by summing the two different digital outputs generated by each filtering arrangement, for example by using a summing circuit. In a preferred embodiment of the invention, a single programmable filter processor is used and is operated in two alternately selected modes, each sharing common filter coefficients. A clock signal alternately selects the two filtering modes. The subsequent outputs from a first mode are delayed and then added to the output of the second mode to produce the desired output signal.
