Hi,
Could you tell me some more details please. Do you want to do it into a computer or do you need an electronics to do the job ? The display is by a computer or the electronics need to have some LCD ?
Please let me know the source signal voltage level.
Still now I haven't worked with this kind of signal, just decoding of ID on taxi caller, but once I get all details I can provide you from schematic through pcb, protos to the final product.
All the best !
Zoltan
