Inventions by Robert Fenton Gary

Brick Wall Filters block all the Frequencies below, and above the one you want.


My snippets are made exactly the same way, with multiple programmable brick wall filters.

What I use is an EDITED version of the full wide peaks profile from 200 nm to 1500 nm.

Just this and that snippets.

A Radio with Digital Tuning Uses Brick Wall Filters. My DSP does that too. Radio and Light are Both Electro-Magnetic Waves.
