  • comparison means, having terminal means to which said device input signal and a reference voltage are applied as inputs, for comparing said input signal with said reference voltage and providing an output signal only when said input voltage rises above the level of said reference voltage; and

    feedback means, to which said device input signal is applied, for producing said reference voltage and automatically maintaining it at a predetermined proportion of the peak noise level of said device input signal, a portion of said reference voltage being fed back as an input reference level to said feedback means.
