VOLTAGE TO FREQUENCY CONVERTER + 1uS LED PULSE DRIVER


Posted on Feb 5, 2014

This circuit receives the signal from the above amplifier and launches powerful 1uS infrared light pulses from a low cost LED that are frequency modulated by the audio information. The 10KHz center frequency of the pulse stream is low enough so a standard infrared LED can emit ten times more light than conventional long pulse techniques. The circuit is descr..
