@ audioguru,

the sum of the absolute value of + .27V and -.27V equals 540mVp and not 540mVp-p

I set the function generator to 540 mVp which is 1.08Vp-p which is not correct.

I should have set it to 270mVp (millivolt peak) and measured that in Vpp units.

I ran the simulation again at 8 volts (because of the clipping at 5V) the output is

5.94Vpp the gain is more than 10. I expected 5.40Vpp an error of 0.54Vpp

So I compensated for the error usng the value for R1 = 9.05K which gives an output of 5.40Vpp

this will help in the future, Measure Vpp input and measure Vpp output then compensate.

thanks for pointing that out.

I am sorry, yes I made an error. As per the schematic givenNo. If R1 is 4k and R2 is 1k then the voltage gain is 5.0, not 10.

No again. If VRMS is 1.0V then V P-P is 2.828V. If Vpeak is 1.0V then VRMS is 0.707V.
