SOP generally gives a HIGH(1) output when the conditions are met, while POS gives a LOW(0) output when the conditions are met.
- For a 2-input AND gate, the SOP expression might be 𝐴⋅𝐵. The overall SOP expression for a larger circuit combines multiple such terms using OR operations.
- For a 2-input OR gate, the POS expression might be (A+B). The overall POS expression for a larger circuit combines multiple such terms using AND operations
