Figure 4. Spectral Noise Density
Figure 5. Burst Noise Test Circuit
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
µV peak limit
refers to the operational amplifier input thus eliminating errors
in the closed loop gain factor of the operational amplifier .
