Abstract
Inventia se refera la o interfata specializata ce poate fi plasata într-un micocalculator, destinata asigurarii transmiterii si receptionarii de coduri multitonale secventiale prin radiotelefon. Un echipament astfel constituite poate intra în compunerea unor retele radiotelefonice de transmisie de date, cum ar fi retelele de control centralizat prin radio al proceselor tehnologice cu arie mare de acoperire (exploatari petroliere, cariere, irigatii, transporturi, etc.). Interfata este formata dintrei parti principale si anume: -un generator de semnale multitonale, care pe baza comenzilor primite de la microcalculator, furnizeaza la borna AF modulatie a radiofonului semnalele multitonale specifice codului utilizat; -un circuit de recunoaster e a frecventelor corespunzatoare semnalelor multitonale care masoara perioada fiecarei sinusoide a semnalului de AF receptie primit de la radiotelefon si furnizata microcalculatorului informatii supra acelor perioade care corespund valorilor semnalelor multitonale ale codului; -un cuptor de magistrale.
