AbstractThe traditional use of active RC-type filters to provide anti-aliasing filters in Pulse Code Modulation (PCM) systems is being replaced by the use of Digital Signal Processing (DSP). This is especially true when performance requirements are stringent and require operation over a wide environmental temperature range. This paper describes the design of a multi channel digital filtering card that incorporates up to 100 unique digitally implemented cutoff frequencies. Any combination of these frequencies can be independently assigned to any of the input channels.
