Conectare filtru electromecanic (EMF-500, etc)


Recommended Posts

Daca veti cauta spre sfirsit veti descoperi filtre electromecanice de la 64KHz la 108KHz, aceasta fiind grupul primar din cadrul sistemelor telefonicede curenti purtatori cu multiplexare in frecventa.

Elegant si performant, nu chinuieli de genul filtre de banda LC sau sa formezi SSB in 200KHz si apoi sa`l duci in spectrul dorit prin mixari, si solutia asta fiind mai performanta decit filtrele LC.

Ar fi fost un vis si pentru cei care au lucrat in telefonie sa aiba astfel de sisteme, ale noastre...iti mincau zilele cu filtre si condensatori stiroflex!
