Abstract The matched filter has one memory circuit to maintain the elements of input ordinal number, one multiplication circuit to multiply the elements maintained in the memory and corresponding joint factor, one sum circuit to add the outputs of the multiplication circuit, and one shift unit to shift the output of the sum circuit. By means of one subtration unit, one addition unit and one additional memory circuit, the present invention ordinal number sum is found out based on the first and the last element of the maintained input ordinal number and the preceding input ordinal number sum, which is subtracted to produce a filtering output.
