Half Subtractor and Full Subtractor
Half subtractor and full subtractor are the combinational logic circuits used in digital computer systems. Digital computers perform number of computations in their lifetime. In which, subtraction is one of…
Half Adder and Full adder
A digital computer performs different operations with devices like half adder, full adder, half subtractor, full subtractor, parallel adder, BCD adder, multiplexer, demultiplexer, decoder, encoder, code converters, etc. Theses circuits…
Different Types of Transformer
There are different types of transformers based on the application, nature of use and number of phases. Based on the application, transformers are widely used in the electric power system…
Universal Logic gates
Universal logic gates are used to build all other logic functions. NAND gate and NOR gate are known as universal logic gates. With these two gates, other logic functions like…
Logic Gates
Logic gates are the basic building blocks of any digital system. Generally, a digital circuit will consists of number of logic gates, which receive the binary inputs and perform a…
Minimization of Boolean function using k-map
The Karnaugh map or K-map is used for minimization or simplification of Boolean function either in Sum of Product(SOP) form or in Product of Sum(POS) form. Before proceeding with the…
Plotting Karnaugh Map with examples
Simplification of Boolean expression by using postulates and theorems of Boolean algebra can never be the simplest possible expression. So we use the Karnaugh map or K map to simplify…
Sum of Product and Product of Sum Form
Sum of Product and Product of Sum Form are the two forms of boolean expressions. Generally, Boolean expressions are built with constants and variables. These expressions describe the Boolean function….
Postulates and Theorems of Boolean Algebra
Boolean algebra is a system of mathematical logic, introduced by a mathematician George Boole in 1854. Boolean algebra differs from ordinary algebra and binary number system. It is a binary…
