Please log in for more thread options I'm trying to simulate an ADSL filter in Multisim. I got all the components as they were connected in a real filter but there some things I don't understand and I must add that I'm quite new to electronics. The filter's PCB has 2 pins for Line-in, 2 for ADSL-out and 3 for the phone-out (UK phone), where 2 of them are just connected in parallel to a capacitor. Why there a 3 on the phone output not 2 like on the Line input? I noticed that the ADSL socket is directly connected to the Line so as it should be all the signal from the Line goes straight to ADSL modem or router. On the other hand signal coming out from the Phone socket passes through the filter, where all the high frequencies are attenuated. The problem is now how to represent all these sockets in Multisim? Would resistors do? If yes, then what values should they have? Then if I want to connect a Bode Plotter to the circuit it needs an AC source. Where to connect it? Should it be connected to the Line? What voltage and frequency should it have? Any help would be greatly appreciated yaro | ||||||||||
