Hello,

The following is a Data waveform modulated as shown in the image. Can someone guide me how to generate the waveform using a MCU / FPGA. I am trying to figure out how to jump between the voltage rails quick enough to generate an acceptable waveform.

Easy to do with a micro. Get one that has a D/A capability. You only need twio bits, many PICs have a 6 bit one, or you could even use two outputs and a resistor ladder.

Bob, I searched through my PIC datasheets I have in stock but I can't find any with two or even one utputd. Sending this stuff on your smartphone? You need smaller thumbs!:p

Yes, I actually did post that from my smartphone. Don't know how it got through. I meant to say 2 outputs.

Actually, I knew you meant "two outputs" but I couldn't resist! :)
