| The device of the present invention is used to measure the intensity of a disturbing wave and measures an average value of impulsive noise. The invention permits accurate and short-time measurements. Impulsive noise, which is input via a variable attenuator, a frequency converter, an intermediate-frequency amplifier and a band-pass filter of a 9 or 120 kHz pass frequency, is provided to a linear detector. The detected output is applied to a low-pass filter which is composed of CR elements and whose cut-off frequency is tens of kilohertz. By the low-pass filter, the peak value of the detected output is lowered and its width is increased. The filter output is converted by an A-D converter to a digital signal. Digital values at respective sample points in the digital signal of one frame are added by an arithmetic circuit, and the added value is divided by the number of samples to obtain an average value, which is displayed. | ||||||

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. | ||||||
