Abstract: An electronic device is provided for quantifying video frequency pulse signals, comprising a first and a second signal-formation channel having a common input connected to a source of input signals and outputs connected to a level comparator with two output states; the ratio of the gains and the DC level difference of said first and second channels having predetermined values; the first channel comprising a delay circuit provided with substantially equidstant taps which are connected respectively to the inputs of an "OR" type linear operator, the output of this operator being connected to a first input of a summing circuit whose second input is connected to a DC voltage source, the second channel comprising essentially a delay circuit.
