Conversion of Digital Data to Digital Signal involves three techniques: Line Coding Block Coding Scrambling Out of which Line coding is always needed, block cod
Flip flops can be used to store a single bit of binary data (1or 0). However, in order to store multiple bits of data, we need multiple flip flops. N flip flops
Prerequisite – Counters, n-bit Johnson Counter A counter is basically used to count the number of clock pulses applied to a flip-flop. It can also be used for
According to Wikipedia, in digital logic and computing, a Counter is a device which stores (and sometimes displays) the number of times a particular event or pr
Ring counter is a typical application of Shift resister. Ring counter is almost same as the shift counter. The only change is that the output of the last flip-f
In this article we try to explain the fundamental differences between Register Transfer Level (RTL) Design and Sequential Logic Design. In the RTL Design method
Prerequisite – Mealy and Moore machines A sequence detector is a sequential state machine which takes an input string of bits and generates an output 1 whenev
Digital Signal – A digital signal is a signal that represents data as a sequence of discrete values; at any given time it can only take on one of a finite num
Digital Signal: A digital signal is a signal that represents data as a sequence of discrete values; at any given time it can only take on one of a finite number
Binary is a base-2 number system that uses two states 0 and 1 to represent a number. We can also call it to be a true state and a false state. A binary number i
A set of operations is said to be functionally complete or universal if and only if every switching function can be expressed by means of operations in it. A se
In Boolean Algebra, there are three basic operations, which are analogous to disjunction, conjunction, and negation in propositional logic. Each of these operat
Prerequisite – Properties of Boolean algebra, Minimization of Boolean Functions Redundancy theorem is used as a Boolean algebra trick in Digital Electronics.
Full Adder is the adder which adds three inputs and produces two outputs. The first two inputs are A and B and the third input is an input carry as C-IN. The ou
A full subtractor is a combinational circuit that performs subtraction of two bits, one is minuend and other is subtrahend, taking into account borrow of the pr
A magnitude digital Comparator is a combinational circuit that compares two digital or binary numbers in order to find out whether one binary number is equal, l
BCD stand for binary coded decimal. Suppose, we have two 4-bit numbers A and B. The value of A and B can varies from 0(0000 in binary) to 9(1001 in binary) beca
An Encoder is a combinational circuit that performs the reverse operation of Decoder.It has maximum of 2^n input lines and ‘n’ output lines, hence it encode
In Digital Electronics, discrete quantities of information are represented by binary codes. A binary code of n bits is capable of representing up to 2^n distin
Latches are basic storage elements that operate with signal levels (rather than signal transitions). Latches controlled by a clock transition are flip-flops. La
A hazard, if exists, in a digital circuit causes a temporary fluctuation in output of the circuit. In other words, a hazard in a digital circuit is a temporary
It is a combinational circuit which have many data inputs and single output depending on control or select inputs. For N input lines, log n (base2) selection
Digital Electronics and Logic Design Digital electronics or digital (electronic) circuits are electronics that operate on digital signals. In contrast, analog c
