<p>A level indicating system adapted to provide an indication of the maximum peak and analog value of an input signal varying in amplitude. The system is comprised of a shift register which is supplied in series with pulses with the number corresponding to the level of an analog signal, a first circuit which differentiates the series output from the shift register to provide pulses, a second circuit which prohibits the pulses derived from the first circuit except the first pulse thereof, a third circuit which adds the pulse from the second circuit to a following information to be applied to the shift register, and a device which displays the content of the shift register.</p> |
