I'm currently delving into audio stuff. I was wondering how exactly
does an RMS detector work. I can picture how a peak detector works,
but if you send a speech signal to an RMS detector, how does it
compute the RMS value?
One way is to dump it into a resistive load and measure the temperature rise
of the load. By the way, equal dc and rms voltages cause the same
temperature rise in a given load.
