Hi all,
I'm trying to do A/D conversion for a voice coming from an analog phone. Could you please give me some advice. Like, do I need an amplifier to amplify the analog signal coming from the phone? If so, please advice me some amplifiers. I will be doing this A/D conversion on PIC18F4550. Do you have any examples of voice to digital conversion of PIC? Thank you so much!
