If the input to the ideal comparator shown in figure is sinusoidal signal of 8V (peak to peak) without any DC component, then the output of the comparator has a duty cycle of

If the Op-Amp in the figure is ideal, the output voltage V_out will equal to

An amplifier without feedback has a voltage gain of 50, input Resistance of 1 k$$\Omega $$ and output Resistance of 2.5 k$$\Omega $$ . The input Resistance of the current-shunt negative feedback factor of 0.2 is

If the differential voltage gain and the common mode voltage gain of a differential Amplifier are 48 dB and 2 dB respectively, then it's common mode Rejection Ratio is
