The circuit shown in figure uses an ideal op-amp working with $$+5V$$ and $$-5V$$ power supplies. The output voltage $${V_0}$$ is equal to

A major advantage of active filters is that they can be realized without using

The circuit shown in Figure, acts as a ... and for the given inputs, its output voltage is . . . . . $$V.$$

Let the magnitude of the gain in the inverting op - amp amplifier circuit shown be $$x$$ with switch $${S_1}$$ open. When the switch $${S_1}$$ is closed, the magnitude of gain becomes.
