Abstract

Arrangement of circuits to produce a regulatory signal as a function of the phase difference between a command signal and a reference signal, an arrangement comprising at least two rectifiers and their associated circuit elements, in which the sum of the two signals is supplied to an input terminal of a rectifier and the difference is supplied to an input terminal of the other rectifier, the two output terminals of the rectifiers being coupled to an output capacitor; said circuit arrangement characterized by the fact that the circuit elements comprise at least one blocking capacitor which, together with the apparent parallel combination of two known resistors, also associated with the circuit elements and connected in series between the two rectifiers, constitute a capture or retention system equipped with a time constant greater (for example, 5 to 10 times greater) than a period of the command signal, also having an auxiliary source of voltage of value and polarity such that the two rectifiers are blocked when the command signal disappears.
