Laboratory Exercise 3 Consider the RRC circuit network in Fig. 4, based on the differential equation relating x you obtained from the pre-lab exercise, if ) and y that C0.2F, R R-10,perform the following: i. Plot the zero-input response if the initial voltage across C is 3V; i. Plot the total output response y) if the input signal is a 0.4u() and the initial voltage across C is 3V; Plot the output response y(t) f the input signal is 0.4 cos(2 )u(t) and the initial voltage across C is 3Vv. iii. Label your plots properly
