A digital system is a combination of devices designed to manipulate logical information or physical quantities that are represented in digital form; that is, the Read More »

Why Binary? The number system that you are familiar with, that you use every day, is the decimal number system, also commonly referred to as Read More »

BOOLEAN CONSTANTS AND VARIABLES Boolean algebra differs in a major way from ordinary algebra because Boolean constants and variables are allowed to have only two possible Read More »

1- The NAND Gate as a Universal Logic Element The NAND gate is a universal gate because it can be used to produce the NOT, the Read More »

Boolean Addition In Boolean algebra, a sum term is a sum of literals. In logic circuits, a sum term is produced by an OR operation with Read More »

BINARY CODES In the coding, when numbers, letters or words are represented by a specific group of symbols, it is said that the number, letter Read More »

1 BINARY ADDERS One of the most important tasks performed by a digital computer is the operation of adding two binary numbers. The simplified Read More »

As its name indicates, a decoder is a circuit component that decodes an input code. Given a binary code of n-bits, a decoder will tell which Read More »

A multiplexer or MUX, also called a data selector, is a combinational circuit with more than one input line, one output line and more than Read More »

FLIPFLOPS The basic 1-bit digital memory circuit is known as a flip-flop. It can have only two states, either the 1 state or the 0 state. Read More »

Counting is frequently required in digital computers and other digital systems to record the number of events occurring in a specified interval of time. Normally Read More »

REGISTERS A register is a group of binary storage cells capable of holding binary information. A group of flip-flops constitutes a register, since each flip-flop can Read More »

READ-ONLY MEMORY (ROM) A read-only memory (ROM) is a device that includes both the decoder and the OR gates within a single IC package. The connections Read More »

What is ADC ? An electronic integrated circuit which transforms a signal from analog (continuous) to digital (discrete) form. Analog signals are directly measurable quantities. Digital Read More »

Till now we studied the logic circuits whose outputs at any instant of time depend only on the input signals present at that time are known Read More »

An S-R flip-flop has two inputs named Set (S) and Reset (R), and two outputs Q and Q’. The outputs are complement of each other, i.e., Read More »

Generally, synchronous circuits change their states only when clock pulses are present. The operation of the basic flip-flop can be modified by including an additional Read More »

Circuits in which all outputs at any given time depend only on the inputs at that time are called combinational logic circuits. A combinational circuit Read More »
