I'm new to this field. I've connected the earphone jack to my cell phone and have stripped the front part of both left and right side of earphone. There I see two wires in each of it. What does those 2 wires mean???
I want to amplify the signal directly as electrical signals only. So I'm trying it with the basic amplifier circuit using 741 op-amp. Will it work??
I've to give the amplified signal to ADC though.
