A chemical plant needs a microprocessor-driven alarm system to warn of critical condition in one of its chemical tanks. The tank has four HIGH/LOW (1/0) Switches that monitor temperature (T). Pressure (P) fluid level (L) and weight (W). Design a system that will notify the microprocessor to activate an alarm when any of the following conditions arise: 1. High fluid level with high temperature and high pressure.
2. Low fluid level with high temperature and high weight
3. Low fluid level with low temperature and high pressure.
4. Low fluid level with low weight and high temperature.

Answer following questions:

a. Write the Boolean equation in the simplest form (using Karnaugh map to optimize) to implement the system above.
b. Use complementary CMOS design to realize the function above.
c. Use pseudo-NMOS realization to implement the function above.
d. Use Pass Transistor Logic to implement the function above.
