Claim 5:
6. The band filter (200) of claim 5, wherein the high-pass higher order polynomial regression based zero frequency centered band filter (230) further comprises:
a feed forward loop (234) communicatively coupled to the input frequency shifter (220), the feed forward loop (234) being configured to receive the frequency down shifted discrete time series signal (220a) provided by the input frequency shifter (220); and
a summation (236) communicatively coupled to the polynomial regression filter (232) and the feed forward loop (234), the summation (236) being configured to:
receive the smoothed frequency down shifted time series signal (232a) from the polynomial regression filter (232);
receive the frequency down shifted time series signal (220a) from the feed forward loop (234); and
sum the smoothed frequency down shifted discrete time series signal (232a) and the frequency down shifted discrete time series signal (220a) to provide a filtered and frequency down shifted discrete time series signal (230a).
