But, an RC circuit's speed changes with battery power.  Then it wouldn't 
be very accurate.

There were in this country two very large monopolies.  The larger of
the two had the following record: the Vietnam War, Watergate, double-
digit inflation, fuel and energy shortages, bankrupt airlines, and the
8-cent postcard.  The second was responsible for such things as the
transistor, the solar cell, lasers, synthetic crystals, high fidelity
stereo recording, sound motion pictures, radio astronomy, negative
feedback, magnetic tape, magnetic "bubbles", electronic switching
systems, microwave radio and TV relay systems, information theory, the
first electrical digital computer, and the first communications
satellite.  Guess which one got to tell the other how to run the
telephone business?
