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 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, 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 »

Overview In digital electronics, codes are used to represent information in a binary format. Parity is a technique used to detect errors in data transmission Read More »

Arithmetic circuits are digital circuits designed to perform arithmetic operations on binary numbers. They are an essential component of digital systems, such as microprocessors, calculators, Read More »

Decoders and encoders are fundamental digital circuits used in digital electronics. They are designed to convert between different representations of data, such as binary codes, Read More »

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

Sequential Logic Circuits Till now we studied the logic circuits whose outputs at any instant of time depend only on the input signals present at that 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 »

Combinational logic refers to a type of digital logic circuit in which the output depends solely on the current inputs. It doesn’t have any memory Read More »
