Abstract
The invention relates to a digital circuit making it possible to measure the effective voltage of a signal, comprising at least one module exhibiting a sampler stage exhibiting an output generating an output logic signal which, for each given sampling period, exhibits a level representing the value of the voltage of the signal with respect to a given threshold (A), characterized in that it comprises a circuit (CIRC) for calculating a value representative of said effective voltage as a function of the difference between the number of times the output logic signal indicates that the voltage of the signal is above the given threshold (A) and the number of times the output logic signal indicates that this value is below said given threshold (A) over a duration corresponding to N given sampling periods.
