Explanation Given data: Refer Figure 3.121 in the textbook for mesh analysis. Calculation: Apply Kirchhoff’s voltage law to loop with current I o in Figure 3.121. ( 4 k Ω ) I o + ( 15 mV ) − v o 100 = 0 ( 4000 Ω ) I o + ( 0.015 V ) − 0.01 v o = 0 { ∵ 1 k Ω = 1000 Ω 1 mA = 1 × 10 − 3 A } − 0.01 v o + ( 4000 Ω ) I o = − ( 0.015 V ) (1) From Figure 3.121, write the expression for the voltage v o . v o = ( 20 k Ω ) 50 I o v o = ( 20000 Ω ) 50 I o v o = ( 1 × 10 6 Ω ) I o (2) Substitute equation (2) in (1). − 0.01 ( 1 × 10 6 Ω ) I o + ( 4000 Ω ) I o = − ( 0

3. You have come to encounter an LTI system. You have no idea how the system behaves. So, you decide to drive the system with a particular input and measure the output. When you put the input u(t) = et 1(t), you find that the output y(t) = (1-e) 1(t). You can assume zero initial conditions. Now, find the transfer function of the system.
