That is an interesting part.
So, how does one think about reverse isolation in a feedback amp? Is the
open-loop gain of the amp applied to the spurious signal to cancel it? The
spurious, reduced by the ratio of the 50 ohm source impedance, to the output
impedance of 0.7 ohms of the amp (-18 dB) appears at the inverting input . . .
And what would appear at the non-inverting input?
Off to the simulator.
