    You can derive a Boolean expression from a truth table using either the Sum-Of-Products (SOP) or Product-Of-Sums (POS) method, depending on whether you focus on output 1s or 0s.

    Method 1: Sum-Of-Products (SOP)

    1. Identify all rows in the truth table where the output is 1.

    2. For each such row, write a Boolean product term that equals 1 for that exact input combination (use complements for 0 inputs).

    3. Combine all product terms using the + (OR) operator to form the SOP expression.

    4. Optionally, simplify the SOP expression using Boolean algebra rules.

    Method 2: Product-Of-Sums (POS)

    1. Identify all rows in the truth table where the output is 0.

    2. For each such row, write a Boolean sum term that equals 0 for that exact input combination (use complements for 1 inputs).

    3. Combine all sum terms using multiplication (AND) to form the POS expression.

    4. Optionally, simplify the POS expression using Boolean algebra rules.

    Implementation Notes

    1. SOP expressions are implemented as AND gates feeding into a single OR gate.

    2. POS expressions are implemented as OR gates feeding into a single AND gate.

    3. Both methods can be directly translated into logic circuits or relay logic designs.
