Abstract

Anordningen i henhold til oppfinnelsen er bestemt for å modulere pulsene i et utgangssignal (V) avledet av et analogt lnngangssignal (V) og omfatter innretninger (3) for å generere et differansesignal mellom en avbildning av inngangs-signalet og en avbildning av utgangssignalet, og innretninger for å styre et nivå av utgangssignalet slik. at differansesignalet har en verdi som i gjennomsnitt er lik null.The device according to the invention is intended for modulating the pulses in an output signal (V) derived from an analog input signal (V) and comprises means (3) for generating a difference signal between an image of the input signal and an image of the output signal, and devices for controlling a level of the output signal thus. that the difference signal has a value which on average is equal to zero.
