DSP for beginners - Decoding FSK
Please excuse me. I am a complete NOOB when it comes to DSP. I am familiar with Fourier-transform (And Walsh) and D/A - A/D conversion, but have never done anyhing DSP-like, except for recording, delaying, and playing sound.
I am looking at decoding FSK, specifically SITOR-B which has a 170Hz shift with a bitrate of 100bps and need to find something to get me started. Should I go the FFT-route or simply create two filters for mark and space and output that to logic.
Any pointers to good self-study resources are appreciated!
