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 …

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 …

Digital Decoder and its application in digital circuits

Unlike encoder which converts its 2N input lines into N digits binary number according to input line which is on logic high, digital decoder decodes that encoded N digit binary number and turns an output line high out of its 2N output lines corresponding to that binary number. It is also a combinational circuit and …

Bitwise operators in Arduino

In previous two tutorials we have discussed about arithmetic and relational operator. There are following types of operator. Arithmetic operators Relational (comparison) operators Bitwise operators Boolean (logical) operator Arduino buying links Amazon link for India Amazon link for other countries In this tutorial we will see about bitwise operators. Bitwise operators Bitwise operators performs bitwise …

Latches and Flip Flops

Latches and flip flops are memory device. It can store previous values. There are two types of digital circuit, sequential and combinational digital circuit. Latches and flip flops are sequential digital circuit. When feedback from output is provided to input that circuit is called sequential circuit and in combinational circuit there is no any feedback …

Number System for digital electronics

Number system is technique to write or represent the numbers. Most commonly used system is decimal number system. But in the electronics field there are some more number systems comes to know. Which are – Binary number system Octal number system Hexadecimal number system Now, I am going to explain about all of them one …
