Abstract
Inventia se refera la tehnica de masurare si la radioelectronica si poate fi utilizata pentru reproducerea cu precizie inalta a admitantelor flotante reprezentate in coordonate carteziene. Convertorul de admitanta contine doua contacte (2, 3), un amplificator diferential (1), intrarile neinvertoare si invertoare ale caruia sunt conectate la contactele (2, 3) respectiv, doua amplificatoare programabile (4, 5) cu coeficienti de transfer reglabili in intervalul de valori pozitive si negative, intrarile carora sunt conectate la iesirea amplificatorului diferential (1), un defazor (6) cu defazaj de 90°, intrarea caruia este conectata la iesirea amplificatorului programabil (4), doua convertoare de tensiune in curent (7, 8) cu coeficienti de conversie egali, iesirile carora sunt conectate la contactele (2, 3), respectiv. Convertoarele de tensiune in curent (7, 8) sunt dotate cu intrari diferentiale. Iesirea amplificatorului programabil (5) este conectata la intrarea neinvertoare a convertorului de tensiune in curent (7) si la intrarea invertoare a convertorului de tensiune in curent (8), iar iesirea defazorului (6) este conectata la intrarea invertoare a convertorului de tensiune in curent (7) si la intrarea neinvertoare a convertorului de tensiune in curent (8).
