modulation
 
hello everyone,
can you guide me on how to write the code of modulation in c.
i have carrier signal of 38Khz and i want to superimpose my data signal on it.
when i detect high signal of 38Khz, i will pass the data.
when i detect low signal of 38Khz, i will not pass the data.
when again i detect high signal of 38Khz, i will again pass the remaining data.
pls guide me on this
i will be interfacing this with arm processor i.e LPC2378. but i want logic for modulation.
thank you
