Basic Logical Operations

Item Code: SJ257

Principle and Working:

De Morgan's Law
De Morgan's Laws are fundamental principles in Boolean algebra and logic that describe the relationship between the logical operators NOT, AND, and OR. They allow you to express the negation of compound logical expressions in terms of the negation of individual components.
De Morgan's First Law states that the negation of a conjunction (AND) is equivalent to the disjunction (OR) of the negations of the individual components.
... Logic gate
A "quad logic gate module" typically refers to an integrated circuit (IC) package that contains four individual logic gates. Each gate within the module is typically of the same type, such as an AND gate, OR gate, XOR gate, or other logic gates.
The purpose of a quad logic gate module is to provide a convenient and compact way to implement multiple logic gates in electronic circuits.




  • AND, OR, XOR, NOT, NAND and NOR operations using single logic gate modules.
  • De Morgan’s laws
  • AND, OR, XOR, NOT, NAND and NOR operations using quad logic gate modules.
  • Students use plug-in modules for circuit design.
  • Component mounted on PCB and these PCB fix in a transparent housing for the visibility of the components.
  • The symbol's name and the value of the components are printed on top of the transparent housing.
  • Convenient & Easy to make circuit diagram using plug-in modules.
  • Do it yourself approach provodeds better learning.
  • Economical & Flexible method of performing all experiments on one circuit board.
