Abstract

Inventia se refera la tehnica de masurare si radioelectronica si poate fi utilizata pentru reproducerea cu precizie inalta a impedantelor flotante comandate in tensiune cu orice caracter si cu posibilitatea reglarii independente a modulului si a fazei impedantei reproduse. Convertorul de impedanta contine doua contacte, un amplificator programabil, iesirea caruia este conectata la intrarea unui defazor programabil, conectat cu iesirea la intrarea unui convertor de tensiune in curent, iesirea caruia este conectata la primul contact. Convertorulde impedanta contine suplimentar un al doilea convertor de tensiune in curent, conectat cu intrareala iesirea defazorului, iar cu iesirea - la al doilea contact, precum si un amplificator diferential conectat cu intrarile la contactele mentionate si cu iesirea la intrarea amplificatorului programabil. Totodata convertoarele de tensiune in curent asigura coeficienti de conversie cu valori egale si cu semne opuse, iar amplificatorul diferential poseda impedante de intrare mult mai mari decat impedantele circuitului extern conectat la primul si al doilea contacte. Rezultatul inventiei consta insporirea preciziei de reproducere a impedantelor simulate flotante cu reglare independenta a modulului si a fazei impedantei reproduse.
