Abstract

Amplitudereguleringskrets (REG) som regulerer; henimot en referanse-amplitude (VR); en amplitude for en pulsbølgeform som genereres over en belastningsimpedans (L) av en såkalt H-avgrening; idet minst en av avgreningens svitsjer har en vari- abel impedans. Amplituderegulerings- kretsen (REG) innbefatter en måleinnret- ning (Cl) som måler amplituden under de fcrste deler av pulsbølgeformen og en reguleringsinnretning (OA,C2,CS1,S2,S3,- Q5,CS2,S4,S5,Q6) som styres av måle- innretningen (Cl) under de andre deler av pulsbølgeformen og som regulerer den variable impedans og dermed regulerer pulsbølgeformens amplitude.Amplitude control circuit (REG) which regulates; towards a reference amplitude (VR); an amplitude of a pulse waveform generated over a load impedance (L) of a so-called H branch; with at least one of the branch switches having a variable impedance. The amplitude control circuit (REG) includes a measuring device (C1) that measures the amplitude under the first portions of the pulse waveform and a control device (OA, C2, CS1, S2, S3, - Q5, CS2, S4, S5, Q6). of the measuring device (C1) under the other parts of the pulse waveform and which regulate the variable impedance and thus regulate the amplitude of the pulse waveform.
