5. Find ux (t) in the circuit given. 100 cos 40r V 100 501 0.1 H + 0.005 F m 0.2 H 40 cos (40% - 30%) V

thanks

Ques. 7: Simplify the following: (a) [e-tcos(3t – 60°)]8(t) (b) 8(t + 3)e-t

sgn (t) = 2u(t) – 1 check graphically

I need answer within 20 minutes please please with my best wishes

Q. Find Ex and Ey, the energies of the signals x(t) and y(f) shown in Figure. Sketch the signals x(t) + y(t) and x(t) - y(t) and show that the energy of either of these two signals is equal to Ex + Ey x(1) y(t) 1 1 2n -1 -1

A linear system is described by the differential equation dy² dy du +5 +6y=2- +1 dt² dt dt Find the system poles and zeros and plot their diagram.

It should contain your answers, graphics, and MATLAB codes in a clear sequence order. Q1. Consider the differential equation: dy(t) + 2y(t) = 2x(t) %3D dt Let the input signal be a sin wave: x(t) = sin(t) For t>0 and initial condition of y(0) = 0 Find and plot the solution y(t) inMATLAB

please sketch relevant circuits, graphs, phasors, and all signals that are changing with time
