hello people
I'm new to embedded, so please be patient with me. I want to capture a typical remote controllers IR signal. I'm aware of the different protocols and their decoding process. My question is this, can I NOT decode the signal and just record it using the timer and just playback the stream using the same sampling frequency? Theoretically with regards to Nyquist sampling theory if my timer frequency for sampling is double the max frequency of the desired signal, I can rebuild it. IS THIS correct or am I missing something in the big picture? I am using an AVR ATM32 and sampling with a 25 0khz timer in CTC mode.
Any practical or theoretical help will be appreciated.
