An Overview Decoders are used by digital systems to transform encoded data into a more intelligible format. In many different applications, including memory addressing, data routing, and control systems, these essential components are frequently used. The implementation of a decoder using VHDL (Very High-Speed Integrated Circuit Hardware Description Language) will be discussed in this article. Before physical implementation, designers can model and simulate digital circuits using the potent hardware description language known as VHDL. We'll approach comprehending and putting a decoder into use using VHDL step-by-step. Decoder A decoder is a combinational logic circuit that uses a particular decoding strategy ... Read More

Simplification is an approach in which a Boolean expression is minimized or reduced into an equivalent expression by using some Boolean identities. Boolean algebra is a mathematic applied to binary number system. It was developed by George Boole, an English mathematician, to simplify complex logical operation to their simplest form. The simplification of a Boolean function is important because it reduces the number of logic devices/gates required to implement a logic function. This in turn reduces the hardware cost and complexity of the circuit. Also, it increases the reliability of the system. In this tutorial, we will understand the ... Read More

In digital electronics, the binary adder is a combinational logic circuit which performs the addition of two or more binary digits. The binary addition is performed based on the Boolean algebraic laws of addition, i.e., $$0+0=0$$ $$0+1=1$$ $$1+0=1$$ $$1+1=0$$ Binary adders are classified into two types namely, serial binary adder and parallel binary adder. In this tutorial, we will discuss serial binary adder, its definition, logic circuit diagram, and operation. So, let us start with basic introduction of serial binary adder. What is a Serial Binary Adder? A serial binary adder is a binary adder circuit which is used to ... Read More

SOP Form SOP form stands for Sum of Products form. SOP form is one in which a Boolean expression is expressed as a sum of product terms. For example, $$\mathrm{\mathit{f}\lgroup A, B, C\rgroup=AB+ABC+B\overline{C}}$$ This is a Boolean function expressed in SOP (Sum of Products) form. NAND Gate The NAND Gate is a type of universal logic gate. It is a logic gate one that can be used to realize any kind of logical function or any other type of logic gate. A NAND gate is basically a combination of two basic logic gates namely AND gate and NOT gate, i.e. ... Read More

In positional number systems, the radix is the total number of unique digits that are used to represent numbers in that number system. Radix is also called Base. For example, in decimal number system, we use total ten digits from 0 to 9 (i.e. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9) to represent any decimal number. Therefore, for the decimal number system, the radix or base is ten (10). Although we can easily convert a given number from one radix (i.e. number system) to any other radix (number system) by using radix conversion protocols. In this article, ... Read More

In digital electronics, adder and subtractor are the two most basic arithmetic combinational circuits. The adder is a combinational arithmetic circuit used to perform addition of two or more binary numbers. Whereas, the subtractor is a combination arithmetic circuit used to perform subtraction of two binary numbers. Depending on the form in which the addition and subtraction of binary numbers are executed, the adder and subtractor are classified into following types − Serial Adder Parallel Adder Serial Subtractor Parallel Subtractor This tutorial is meant for explaining Parallel Adder and Parallel Subtractor. But before that let us first discuss ... Read More

Any Boolean function or logical expression can be expressed in either canonical/standard sum of products form or canonical/standard product of sums form. The standard sum of products form of a logical expression contains different product terms which are added together, and each product term is referred to as a minterm. On the other hand, the standard product of sums form of a logical expression contains different sum terms which are multiplied together, and each sum term is called a maxterm. In this article, we will discuss about the minterm and max terms. What is Minterm? When a Boolean function or ... Read More
