Hi all,
I've been trying to measure the AC voltage coming out the phone line when I talk, but I don't know for some reasons I've got noise at the output. Could you please tell me the range of this output (it would be good if you show me on the Oscilloscope). And also what chip should I use to amplify this AV signal? Thank you
Tom
