The circuit in Figure 4–17

(a) represents a small-signalmodel of a field effect transistor

(FET) amplifier with two inputs, υS1 and υS2. Use Multisim to solve for the inputoutput relationship of the circuit. (Hint: Use superposition to find the respective gains due to the two sources, for example, υS1 = 1 V and υS2 = 0 V, and vice versa.)
