In accordance with embodiments of the present disclosure, a hybrid finite impulse response filter having a plurality of delay stages comprising a first filter portion and a second filter portion. In some embodiments, the first filter portion may be a high-rate filter portion associated with a first portion of the plurality of delay stages and configured to filter an input signal having a first sampling rate to generate a first intermediate output signal and the second portion may be a low-rate filter portion associated with a second portion of the plurality of delay stages and configured to filter a downsampled version of the input signal at a second sampling rate to generate a second intermediate output signal. In other embodiments, the first filter portion may include an analog filter portion associated with a first portion of the plurality of delay stages and configured to filter an input signal to generate a first intermediate output signal and the second filter portion may be a digital filter portion associated with a second portion of the plurality of delay stages and configured to filter the input signal. |
