PROBLEM-SOLVING:
Topic: "Digital Logic"
A Chemical plant needs a microprocessor-driven alarm system to warn of critical conditions in one of its chemical tanks.
The tank has four (HIGH / LOW) switches that monitor:
- Temperature (T)
- Pressure (P)
- Fluid Level (L)
- Weight (W)
You have to design a system that will notify the microprocessor to activate an alarm when any of the following conditions arise:
- High Fluid Level with High Temperature and High Pressure
- Low Fluid Level with High Temperature and High Weight
- Low Fluid Level with Low Temperature and High Pressure
- Low Fluid Level with High Temperature and Low Weight
Note:
Step 1: Create a truth table with appropriate input-output combinations according to the data given.
Step 2: Since it has 'four input variables', draw a four-variable K-map (Karnaugh Map). After that, transfer the output logic in the truth table to the equivalent cells in the K-map. Get the simplified Boolean expressions using the K-map technique.
Step 3: Construct the logic circuit based on the Boolean expression that you obtained in Step no 2.
