ABSTRACT:
Provided are a system and method for implementing a multirate analog finite impulse response (FIR) filter. A system of the present invention includes a modulator having a first adder and a quantizer. The first adder includes an output port, and the quantizer includes (i) an input port coupled to the first adder output port and (ii) a quantizer output port. A second adder is also included, having one input port coupled to the first adder output port and another input port coupled to the quantizer output port. Also included are at least two two-unit delays, a first of the two-unit delays having an input port coupled to an output port of the second adder, and an output port coupled to an input port of the second of the two-unit delays. An output port of the second two-unit delays is coupled to a first input port of the first adder.
