PULSE_FREQUENCY_MODULATED_RECEIVER

Published:2009/7/17 2:31:00 Author:Jessie | From:SeekIC

This receiver uses an IR-sensitive phototransistor (Clairex, HP, etc.) mounted in a light-tight enclosure with an aperture for the incoming IR beam. An optical system can be used with this receiver for increased range. A 741 amplifies the pulsed IR signal and a 565 PLL FM demodulator recovers the audio, which drives an LM386 audio amplifier and speaker.
