Simon, I enjoyed your filter design. I do have a question though. Could a similar design be utilized in a DSP capable FPGA or MCU that could be used to filter out power supply switching noise from power supplies? They have a know frequency and harmonic pattern, and cause quite a bit of "white" noise on signal lines, and I was curious if the same concept could be implemented to reduce the effects of noise on those signals.
Thanks again for the great filter for the games.
