Follow the instructions. Kindly provide a COMPLETE and CLEAR solution. Answer it ASAP because I really need it right now. Answer should be typewritten. Provide the following:Step 1. Solve for kStep 2. Solve for Tk (forward path gain)Step 3. Identify the loop gains (TL)Step 4. Identify the nontouching loops taken two at a time TNL(2 time)Step 5. Identify the nontouching loops taken three at a time TNL(3 time)Step 6. Identify the nontouching loops taken four at a time TNL(4 time)Step 7. Solve for component ∆Step 8. Solve for component ∆k (Note: We form ∆k by eliminating from ∆ the loop gains that touch the kth forward path)Step 9. Substitute on the equation for transfer function
