[sdiy] Wanted: non mathematical description of the function of RC-filters

[Paul Anderson]

You might use the "little man" model that's used in Art of Electronics to explain transistors. Like there's a little man watching the frequency of the signal, and turning variable resistor in response. As frequency goes up, he turns the resistance down.
