Abstract
A digital mixer-filter-decimator (MFD) is disclosed which is reconfigurable so that it can be used in both modes of operation of a dual mode receiver such as an AM/FM receiver. In either mode of operation the MPD performs filtering and decimation operations on separate data streams containing alternate samples of a digital input data stream. In the FM mode a mixing operation is also enabled to produce a complex output comprising in-phase and quadrature components. The mixing operation is disabled in the AM mode and the filtered and decimated outputs are combined to provide a real output. The same decimator filter can be used in both modes.
