I am currently undertaking a design project for one of my courses and I need some help. I want to build a circuit that you can plug into the headphone jack of an audio device (mp3, ipod etc), and that audio signal to be transmitted at a particular frequency. The signal will be received by a receiver circuit and output through a pair of earphones.
I understand this will be quite challenging, but I am willing to put in effort. I need some advice on basically what I should do/know to get started. Any help would be appreciated.
