## 7-segment HEX decoder

Today seven segment displays are widely used in almost all electronic circuits. It can display number from 0 to 9 and some characters. In this display 7 segments of LED (light emitting diode) is arranged such as it can display these information. Each segment is denoted by small alphabetical letters. One terminal of all those …

## K map in digital electronics

K-map is graphical method to obtain minimal expression from any Boolean algebra and it is most effective method to create or reduce the complexity of any logical circuit in digital electronics. It is also known as Karnaugh map. By this method we can easily simplify and minimize Boolean expression of 3 or 4 variables without …

## Boolean algebra for logic gates

Boolean algebra is the mathematics which is used to create and simplify any complex logical (digital) circuits using logic gates. We can analyze a digital circuit and reduce the complexity of Boolean expression by using laws of Boolean. In Boolean algebra there can be only two values of any variable i.e. true and false or …

## Logic Gates and its implementation using transistors

Logic gates are semiconductor devices. It is the building block of any digital device. It has basically two input terminals and one output terminal. On the input terminals, we provide a digital signal and on the output terminal, it provides a digital output. To know the operations of various types of logic gates we first …
