Hi Michael,
Correction: BW = 1/(2*pi*RC) or about 1600Hz
Gerry R."
I haven't seen anything in this discussion (might have overlooked it)
about the effect of capacitance across the SERIES resistors. AT 60 Hz
the reactance of an 0.27 pF capacitor would be only 10 Gohm if I haven't
slipped a decimal point. That's an awfully high series resistance for
an AC divider and I can't imagine the divider giving accurate results at
power line frequencies.
