Web27 de jan. de 2024 · 3 Answers. Sorted by: 1. Positive logic assigns logic '1' to high voltage and logic '0' to low voltage. Negative logic does the opposite ie. logic '1' = low voltage and logic '0' = high voltage. A truth table only tells you the logic values, not the voltages that produce them. However if you are changing from positive to negative logic then ... WebNOR logic gate is an example of a 2-input, 2-output logic gate. It consists of two inputs, A and B.
