Hello there everyone, I'm new to this forum, found it while googling stuff for a school project.
I'm doing a project in my telecommunications course, and wanted to ask for some help and what not.

I am trying to build an Infrared Transmitter and receiver that will take an RS-232 signal, convert it into TTL, then Pulse Width Modulation would be applied, and then finally transmitted. On the reciever side, basically extracting the orignal TTL signal from the Pulse Width Modulated signal and converting it back to RS-232.
I already know how to convert from RS-232 to TTL, and i've been trying to find information on PWM and IR, and found some articles and schematics.
I wanted to know if anyone could recommend how I should approach this, or tell me of any links or sites with some good information.
I'm mainly concerned about the Pulse Width Modulation, modulating the TTL signal and demodulating it.
Any help would be great! Thanks!
