Design an alarm circuit to be used in a process control system.

Design an alarm circuit to be used in a process control system. Temperature (T), pressure (P), flow (F), and level (L) of a fluid are each monitored by separate sensor circuits that produce a high logic output signal when the following indicated physical conditions exist:

- High fluid temperature
- High fluid pressure
- Low fluid flow rate
- Low fluid level

The alarm circuit output (A) should be high if any of the following physical conditions exist in the system:

(1) The pressure is high when the flow is low.
(2) The temperature is high when either the pressure is high or the level is low.

List the truth table inputs in the order T P F L. Be sure to identify the correct physical conditions for the alarm in the logic truth table.
