Humor.

I'd love to flatter myself into thinking I discovered a new signal
processing filter. After all, I've been saying all along that there
is low hanging fruit all over the place in engineering applications.

But the reality is fundamentally new filters from a mathematics POV
are very rare. They figured out everything related to convolutions in
signal processing decades ago.

Can you think of more than one interpretation of what was posted
above?
