Full duplex communication on 2 wire telephone line
« on: March 23, 2008, 01:56:45 AM »
di ba kapag full duplex dapat may dalawang data channel kayo?  bakit dalawang line lang ang telepono pero pasok ang outgoing at incoming na audio na hindi nagkakaroon ng feedback o kaya naman interference?

wala pa kayo sa telephony?

merong hybrid circuit na ginagamit...it converts the 2 wire from the phone line to 4 wire...matched ang impedances nila kaya hindi mo naririnig na nage-echo yung sinasabi mo...

that's the basic explanation... ;)
