Redesign the delay timer system of Fig 9.1 using only discrete components (Eg. transistors, capacitors and resistors etc, NOT integrated circuits), so your circuit should NOT include a comparator

Part B: (15%)
Q5. Redesign the delay timer system of Fig 9.1 using only discrete components (Eg. transistors, capacitors and resistors etc, NOT integrated circuits), so your circuit should NOT include a comparator chip. Explain your proposed system. Simulate and explain the performance and limitations of the system. How could you improve on the limitations?
