A method and apparatus for analyzing an irregular signal and providing a digital read-out in which the signal is applied to four processing channels. In a first channel, a coefficient of interference is obtained by counting transitions of the signal through several values, multiplying the sum of the transitions. In a second channel for obtaining mean peak value, the signal is rectified, supplied to a comparator also fed with a constant amplitude saw tooth wave and the time interval obtained between the initiation of the saw tooth wave and the instant when the saw tooth wave potential is equaled by a potential representing the signal intensity. In a third channel, a duty factor is obtained by dividing the signal after it has been integrated by its mean peak value. In a fourth channel the number of groups of impulses in the signal is determined.
