<p>There are provided a frequency component isolation filter, method, and program capable of reducing the circuit size and simplifying the processing content. The frequency component isolation filter (100) includes: moving average calculation means formed by delay circuits (110, 112), adders (120, 122), a D-type flip-flop (130), and a coefficient multiplier (132) for calculating N moving averages for the input data; and subtraction means formed by an adder (124) for extracting central input data from the N input data to be subjected to the moving average calculation and subtracting the moving average value from the input data value. Outputs from the adder (124) and the coefficient multiplier (132) are simultaneously extracted.</p> |
