If the emitter resistance in a common-emitter voltage amplifier is not bypassed, it will

Two silicon diodes, with a forward voltage drop of 0.7 V, are used in the circuit shown in the figure. The range of input voltage 𝑉${}_{\text{i}}$ for which the output voltage 𝑉${}_{\text{o}}$ = 𝑉${}_{\text{i}}$, is

The circuit shown represents

For a given sample-and-hold circuit, if the value of the hold capacitor is increased, then

In the circuit shown in the figure, if C = 0, the expression for Y is
