From the blog quoted above: "Advanced DSP can certainly get complicated with quadrature processing, Hilbert transforms, and cascaded infinite impulse response filters, but this series on DSP isn't going to get that complicated."

Gulp. I'm new to DSP, so I'm obviously not going to jump into "quadrature processing," but what would you say are the basic mathematical prerequisites for getting into this kind of thing? What sort of math should you know before you even start?

I'm afraid I don't know that info - I worked with the compiler toolchain and associated libraries so strictly speaking it probably wasn't even necessary to know the basics of signal processing. However it gets -complicated- interesting enough to be challenging, and whatever the next steps are this will at least put the necessary groundwork in place :-)

To get started all you really need is trig. As you progress you'll need more advanced math.
