Frage 358

What does “positive logic” mean in reference to logic devices?

  1. The logic devices have high noise immunity
  2. High voltage represents a 1, low voltage a 0Richtige Antwort
  3. The logic circuit is in the “true” condition
  4. 1s and 0s are defined as different positive voltage levels

Erklärung

Positive logic is a labelling convention: the more positive voltage level is called 1 and the less positive level is called 0. Negative logic reverses that assignment. The convention says nothing about noise immunity or about the current state of the circuit.
