In the circuit shown below the op-amps are ideal. Then $${V_{out}}$$ in Volts is

The following circuit has $$R = 10k\Omega ,\,C = 10\mu F.$$ The input voltage is a sinusoidal at $$50HZ$$ with an $$RMS$$ values of $$10V.$$ Under ideal conditions, the current $${{\rm I}_S}$$ from the source is

An ideal op-amp circuit and its input waveform are shown in the figures. The $$o/p$$ wave form of this circuit will be

A general filter circuit is shown in figure

The output of the filter in above is given to the circuit shown in figure The gain $${V_S}$$ frequency characteristic of the $$0/p$$ $$\left( {{V_0}} \right)$$ will be
