Hi! I know a bit of theory about DSP and I want to take my skills to a higher level. More exactly, I plan on 'understanding' a signal from a wave. And later, recomposing a similar signal, from a function.
My problem is that I don't know where to start. I know I'll need some trigo and Fourier series handy, but that's all I can hint to. I've taken a pretty simple sound, a car engine at a constant speed. I've opened it in a few programs and took a look at the wave, but eh, nothing more ^^
How exactly can I start some practical things into this field? For example, transforming (a part) of that wave into a function?
Thanks.
