I vaguely remember some books suggesting a resistor be added to an inverting amplifier design, but I never understood why. I remember it suggesting a value for R1 to be equal to the parallel resistance of the other two resistors. In retirement now I have the time to pursue answers to questions I never found an answer to. So what is R1 supposed to accomplish? I built a circuit with and without R1 and see no difference.
I used an LM741 with an offset pot if it makes a difference.
Is it not apparent in my circuit?
Is there an equivalent resistor in a non-inverting amplifier?
