#99341 - impedance matching Responding to: ???'s previous message |
hello everyone ,
iam doing a mini project to tramsmit files or data between two computers using the parallel port and the existing power lines . but the problem is how to interface the low voltage digital circuit with the 230 volts power lines. i have seen some circuits on the net (www.designnotes.com)(power line fm intercom etc) , there he has used a transformer and a capacitor to interface but did not mention any ratings or further details about the transformer, can any one help me out of how to inteface the digital circuit to the power lines please mail em to narender_aec_eee@yahoo.com |
