IR Remote Control Modulation Detector

Published:2012/11/21 2:05:00 Author:muriel | Keyword: IR, Remote Control , Modulation Detector | From:SeekIC

A circuit to extract and measure the modulated carrier of an Infra Red remote control. Note that the circuit does not physically separate control pulses from modulation, but amplifies the completereceived signal allowing the waveform to be displayed ideally on an oscilloscope or a frequency counter. Modulation frequencies between 1kHz and several MHz may be measured.
