The RMS volts is the same as the DC volts that gives the same watts.
In fact, the teletronix RMS limiter used an incandescent light bulb as
the rms calculator. There is certainly a 'time constant' associated
with it... get an old speaker voice coil, hold it between your fingers
and run music thru it and turn the volume up and down and it gets
hotter and cooler. The 'crest factor' is the peak to RMS ratio. I was
surprised to see that the RMS seems to track the avg but 3dB higher
for most of the music I've run thru my rms and avg calculator program,
so either you can use an RC which gives a good avg and just add 3dB to
get the rms, or my program is messed up. Anyone else want to run a
wave file thru an rmsser and an averager and see what comes out?
