| Abstract: | The wireless audio link is aimed at transmitting audio using high power infrared beam frequency modulation within a localized farm settlement. The modulation is designed with a linear audio amplifier that drives two infrared diodes connected in series across a distance which is a function of power delivered to the diodes. Distance covered varies with a frequency of 100kHz. This study uses a headphone cable of picking up distant sound signals with a high-gain pre-amplifier, a per-emphasis circuit, an automatic gain control, limiting circuit, an automatic gain control, limiting circuit and an FM pulse width modulator. |
