Ladder logic is a programming language that creates and represents a program through ladder diagrams that are based on circuit diagrams. It is mainly used in developing programs or software for programmable logic controllers (PLCs), which are used in industrial applications.

Venn diagram, graphical method of representing categorical propositions and testing the validity of categorical syllogisms, devised by the English logician and philosopher John Venn (1834–1923). Long recognized for their pedagogical value, Venn diagrams have been a standard part of the curriculum of introductory logic since the mid 20th century.. Venn introduced the diagrams that bear his ...

An arithmetic logic unit (ALU) represents the fundamental building block of the central processing unit of a computer. An ALU is a digital circuit used to perform arithmetic and logic operations ...

In electronics a NOT gate is more commonly called an inverter. The circle on the symbol is called a bubble and is used in logic diagrams to indicate a logic negation between the external logic state and the internal logic state (1 to 0 or vice versa). On a circuit diagram it must be accompanied by a statement asserting that the positive logic convention or negative logic convention is being ...

A Venn diagram (also called primary diagram, set diagram or logic diagram) is a diagram that shows all possible logical relations between a finite collection of different sets.These diagrams depict elements as points in the plane, and sets as regions inside closed curves. A Venn diagram consists of multiple overlapping closed curves, usually circles, each representing a set.

Introduction Subject Programmable logic controllers (PLCs) have become the most predominant control elements for the discrete event control of a mechatronics system.

An explanation of the basic elements of elementary logic. Arguments and Inference The Discipline of Logic. Human life is full of decisions, including significant choices about what to believe.

An explanation of the basic elements of elementary logic. Categorical Syllogisms The Structure of Syllogism. Now, on to the next level, at which we combine more than one categorical proposition to fashion logical arguments.
