[sci.electronics] IR Remote Transmitter

ffang@umaxc.weeg.uiowa.edu (Francis Fang) (04/15/91)

Could anyone out there tell me where I might be able to buy or get info
regarding infra red remote control devices. Specifically, I need info on the 
coded pulses that are sent.

I have tried to "see" the pulses by looking at the output of my remote
control on the oscilloscope but all I get are a series of little spikes.
This I would have assumed to be the coded pulses but I also found that
the waveform on the screen was the same amplitude and frequency no matter
what button I press on the IR Trx.

Any info at all would be greatly appreciated.

Frank.
