For example, if the logic diagram shows that a motor should run when two switches are closed, you should close both switches and see if the motor runs and the test light or the buzzer turns on.

For example, an AND gate outputs 1 only if both inputs are 1, while an OR gate outputs 1 if either input is 1. There are seven basic types of logic gates: AND, OR, NOT, NAND, NOR, XOR and XNOR.

The paper introduces a logic controller design system, called PNAD, supporting UML activity diagrams in version 2.x as a semi-formal specification technique. The system enables transformation of ...

This document presents a method of a logical links structure recognition between elements on diagrams. The applied approach intuitively mimics a human way of recognition that relies on merging already ...
