ABSTRACT OF THE DISCLOSURE: A method and a device for measuring an electric quan- tity average value related to a series of trains of a periodic wave, which wave trains having a variable number of complete periods of the periodic wave and being each produced during a corresponding one of successive time intervals. The mea- suring device comprises a circuit for measuring the elec- tric quantity related to the wave train produced during each time interval considering that the wave train is ininterrupted. A storage circuit memorizes the so measured electric quantity. An impulse is produced in response to each complete period of the periodic wave in each wave train. A first memory counts the number of impulses of the wave train of each odd time interval, multiplies the so counted impulses with the measured electric quantity related to the wave train of the odd interval to produce a multiplied value delivered on an output as the electric quantity average value during the one of the time intervals immediately following the odd interval. A second memory counts the number of complete periods in the wave train produced during each even time interval, multi- plies the so counted periods with the measured electric quantity related to the train of the same, even interval to produce a multiplied value delivered on the output as the electric quantity average value during the time interval immediately following the even one.
