ABSTRACT:
A noise wave is received by a receiver and the received output is supplied to a first signal path composed of a rectifier and a low-pass filter connected to the output side thereof. The received output is applied to a second signal path comprised of an AC amplifier, or a rectifier for rectifying the amplified output, a low-pass filter for filtering the rectified output, and an attenuator for attenuating the filtered output. The outputs from the first and second signal paths are selectively provided to a time constant circuit by means of a switch in accordance with the received noise level. The input to the time constant circuit is converted into a quasi-peak value detected output, which is logarithmically amplified by a logarithmic amplifier and is then provided to an indicator.
