Abstract: A lattice wave digital filter (LWDF), configured for a digital signal processor having hardware resources, can selectively include a first processing unit or a second processing unit according to the hardware resources. The first processing unit has a single multiplier and the second processing unit has a plurality of multipliers. The circuitry of the LWDF is arranged in such a way that the transmission route from a first input terminal to a first output terminal is as long as the transmission route from a second input terminal to a second output terminal.
