is the range of gain values
expected from such a circuit?
An inverting op amp circuit is fabricated with the resistors R, and R2 having x% tolerance (that is, the value of each resistance can deviate from the nominal value by as much as x%). What is the tolerance on the realized closed-loop gain? As- sume the op amp to be ideal. If the nominal closed-loop gain is -100 V/V and x = 5, what
