ABSTRACT:
Methods and systems for processing a signal are disclosed herein and may comprise filtering an input signal and a plurality of saturation limit signals to generate a plurality of filtered input signals. A plurality of summed current input signals may be generated by adding the plurality of filtered input signals to a next input signal. While the summed current input signals are being generated, an saturation select signal is simultaneously determined for an output signal based on the input signal. The input signal and the plurality of saturation limit signals may be filtered utilizing infinite impulse response filter and/or finite impulse response filter.
