2.19 An inverting op-amp circuit is fabricated with the resistors R1 and R2 having x% tolerance (i.e., 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? Assume the op amp to be ideal. If the nominal closed-loop gain is −100 V/V and x = 1, what is the range of gain values expected from such a circuit? ±2x%; −98 V/V to −102 V/V
