We are very familiar with this term encoder, mainly encoding and decoding. But to understand encoding we have to know first what an encoder is? So start with an encoder we should know that it is basically a multiplexer without its single output line. You may follow my previous post on Multiplexer to know encoder …
Here I give you clear idea about a multiplexer and the working principle of it. To know about multiplexer we have to know about what is a multiplexer and how it work? A multiplexer commonly called MUX is also called a data line selector. And MUX is a combinational circuit with more than one input line, one …
Here i discus on half adder and full adder circuit with truth table, block and circuit diagram. Half-Adder As the name suggests half-adder is an arithmetic circuit block by using this circuit block we can be used to add two bits. As we know it can add two bit number so it has two inputs …
A combinational circuit is one where the output of that circuit at any time only depends on the present combination values of inputs. And the output is never depending on any past state value of input combination as well as the previous state output value. Now if we take any example then the logic …
As we know, for any complex digital logic circuit the algebraic expression will be also very complex. And from this expression implementation of hardware is also very difficult and cost effective. So if we can minimize the expression then it will reduce the complexity and also reduce the number of gate used to make the …
It is very basic but very important question that what is a conical form of Boolean expression ? If we take any expanded Boolean expression where each term contains all Boolean variables in their true or complemented form, is also known as the canonical form of the expression. Now take an example to understand the …

It is very vital topic that transforming the product of sums expression into an equivalent sum of products expression. It is a very simple and straightforward process. Multiplying out the given expression Do the simplification of the expression after multiplication. By the above mention process we can easily get the equivalent sum of …
As name suggest, A product of sums expression contains the product of different sum terms, now as like sum of products expression, each term may be either a single literal or a summation of more than one literal. Now take a simple example. Let A, B and C is the different literals of a binary …
As name suggest, A sum of products expression contains the sum of different terms, now each term may be either a single literal or a product of more than one literal. Now take a simple example. Let A, B and C are the different literals of a binary system. Now those literals may connected each …
In Digital systems, there will be 8 digital logic gates with different logic troth table. By using those gates we can design any digital circuit. In bellow you will find those digital logic gates with truth table. AND gate: AND gate is used for doing AND / Multiplication of input signals and generates output accordingly. In bellow …
