Abstract

L'invention permet de connaître simplement et sans grand effort, à partir d'un seul et même signal de mesure, les caracté ristiques d'un quadripôle. A cet effet, le récepteur des mesures 21 comporte un ampli ficateur différentiel 5; dont l'entrée A reçoit le signal de sortie du quadripôle 2 amplifié en 3 et dont l'entrée B reçoit le signal de réféférence VS correspondant au signal de mesure P appli qué à ce quadripôle, ces signaux VS et P étant de préférence des signaux pseudo-aléatoires semblables et, d'autre part, l'am plification en 3 du signal de sortie et le temps de propagation en 11 du signal de référence étant réglés par les organes étalonnés V, DELTA , tau aux mêmes amplitudes et temps de propaga tion, tandis que l'organe de mesure 6 reçoit le signal différen tiel D sortant de l'amplificateur 5. Ce circuit peut être utilisé en particulier pour les besoins de la télévision.
