Decimating Digital Filter

The HSP43220/883 Decimating Digital Filter is a linear phase low pass decimation filter which is optimized for filtering narrow band signals in a broad spectrum of a signal processing applications. The HSP43220/883 offers a single chip solution to signal processing application which have historically required several boards of ICs. This reduction in component count results in faster development times, as well as reduction of hardware costs.
