Changing the input voltage to an op-amp circuit will change its voltage gain.

The difference between the upper and lower trigger points is called the Schmitt trigger.

It takes 4 s for the output voltage of an op-amp to rise from –14 V to +14 V. The slew rate of this op-amp is 3.5 V/s.

An open feedback resistor in an inverting or noninverting op-amp circuit can cause severe clipping of the output signal.

If the frequency of an astable multivibrator is 54.86 kHz then its period is 1.82 s.
