ABSTRACT:
A device for finding a moving average of a signal applied from a signal source includes a first delay circuit for delaying input data sampled in a predetermined sampling period by a time period corresponding to N sampling periods where N is an integer, an accumulator for receiving an output of the first delay circuit and input data to store data of (N-1) terms, and a divider for dividing an output of the accumulator by a coefficient (N-1). The accumulator includes an adder, a second delay circuit for delaying an output of the adder by a time period corresponding to one sampling period, and a subtractor for carrying out subtraction between the output of the first delay circuit and that of the second delay circuit to supply a result of the subtraction to the divider. The adder adds input data and an output of the subtractor. This configuration enables implementation of the device for performing fast moving average processing with a simple configuration.
