Abstract

L'invention concerne un étage d'entrée à circuit de compensation de composante continue. Le circuit de compensation est essentiellement un réseau d'impédance constitué par trois résistances R1 , R2 , R3 montées de manière à former un pi ou un T, les deux résistances extérieures R1 , R3 étant, respectivement, reliées à des sources de tension continue ou de courant continu U1 , U 2 ; I, 2I dont les pôles sont orientés de telle manière et qui sont variables conjointement de telle façon qu'elles se compensent mutuellement à l'entrée et que la composante de courant continu du signal d'entrée et que la composante de courant continu du signal d'entrée puisse être compensée à la sortie. Application notamment aux oscillographes.The invention relates to an input stage with a DC component compensation circuit. The compensation circuit is essentially an impedance network consisting of three resistors R1, R2, R3 mounted so as to form a pi or a T, the two external resistors R1, R3 being, respectively, connected to sources of direct voltage or direct current U1, U 2; I, 2I whose poles are oriented in such a way and which are jointly variable in such a way that they compensate each other at the input and that the direct current component of the input signal and the direct current component of the signal input can be compensated at the output. Application in particular to oscillographs.
