Abstract
A single section digital filter is provided with a digital input signal and includes a serial multiplier having an input responsive to predetermine parameters. An adder/subtractor has an input serially connected to the multiplier output. A first switch serially selects recirculating data from an adder/subtractor output directly or delayed, or the digital input signal. A second input of the multiplier is serially provided with the selected data. A second switch serially and selectively connects delayed selected data to a second input of the adder/subtractor. A latch serially receives delayed data for effecting series/parallel conversion thereof.
