Task 4: (20 Marks) a. Filter circuits are also necessary on the transmission end of the cable, to prevent the AC signals from being shunted by the DC power supplys capacitors, and to prevent the DC voltage from damaging the sensitive circuitry generating the AC voltage pulses as shown in figure 4a. Draw some filter circuits on each end of this two-wire cable as shown in figure 4b that perform these tasks, of separating the two sources from each other, and also separating the two signals (DC and AC) from each other at the receiving end so they may be directed to different loads: (10Marks)

b. A Proportional plus Derivative (PD) system is given in figure 4c with ()=15(+1.1) Calculate the derivative time constant T so that the system will have a damping ratio of =0.3. Also, calculate the settling time. (10Marks)
