Whoever wants to read it.
The opening gets to the points pretty quickly—at the very beginning, it just right on terms like bandlimited impulses and modulated audio. The first article fills a screen and a half on a 24" monitor—the reader can glance at it in seconds, noting the diagrams, and figure out pretty quickly if it's worth reading. Someone who isn't at all in the target audience won't find their way to my website.
As for which DSPers, why limit? A beginner would do well to catch the story of how this evolved along communications, and many will probably get the idea of what "impulse" means by looking at the diagrams. (The biggest stretch is probably AM—ideally, I wanted an interactive widget to explore AM, but I don't have the time—the video will elaborate.) And for long-time DSPers, it would be news for many that samples are impulses and why that means there are always aliased images in the digital domain. No disrespect meant—a good mechanic may not fully comprehend exactly how a carburetor works, or how fuel injection accomplishes the same thing.
I'm not sure what people expect here. I don't recall generally seeing instructions at the start of technical articles, or otherwise, about exactly who should be reading them.
