Unlike conventional peak reading or RMS meters, this system was
especially designed to provide the quick response time essential
to burst (popcorn) noise testing.
The test time employed is 10 sec and the 20 mV peak limit
refers to the operational amplifier input thus eliminating errors
in the closed loop gain factor of the operational amplifier.
