1. A method for asynchronous sampling rate converting, the method comprising: receiving, by one or more processors, an input signal, the input signal having a first sampling rate; filtering, by the one or more processors, the input signal with a plurality of input stages of a set of phasor filters at the first sampling rate to generate a plurality of filtered signals; scaling, by the one or more processors, the plurality of filtered signals utilizing a plurality of output stages of the set of phasor filters to generate a plurality of rescaled signals; and summing, by the one or more processors, the plurality of rescaled signals to generate an output signal having a second sampling rate, wherein the second sampling rate differs from the first sampling rate, wherein the plurality of filtered signals includes a set of complex values; and wherein the plurality of rescaled signals includes a set of real values.
