Has anybody heard about 3-state logic gate. Here is an article describing the basic operation of a 3-state logic gate. Also I have clearly mentioned and explained about the excitation table and its uses. If you read this entire article, you can understand the excitation table.

AC to DC conversion using Rectifiers

In our day to day electrical applications we prefer to use dc than ac. Generation of dc with large power is not economical. And conversion of dc to ac is also a difficult process. But we can generate ac with large power and it's conversion to dc is convenient too. This process is called as rectification. In this article rectification operation of half wave rectifier, full wave rectifier and bridge rectifier are discussed.

Inductor and its function in detail

An inductor (also called inductor or coil) is a passive component. It is neither more nor less than a conductive wire wound around a support or rolled in the open air (without any backing). In this article we are going to discuss it's construction, types, function and characteristics in detail.

Relays and its function in detail

A relay is a device in which an electrical phenomenon (current or voltage) controls the on / off switching of a mechanical element. In this article we are going discuss its operation, construction, types and its uses in detail with neat diagrams.

Optocoupler and its types in detail

An optocoupler is a component or set of components that allows the transfer of information between two electronic parts insulated from each other by an electrical point of view. The first part is a transmitter, and the second part is a receiver. It can be compared to a component which has an input (emitter) and an output (receiver). When we speak of issue this is usually because it emits something. Here, there is an emission of light. Hence the prefix of Opto . This is the detailed article on Optocoupler.

ZIGBEE (Wireless) based projects for Instrumentation Engineering

This article is deals with the automatic control of temperature control valve by using closed loop control system of temperature. The data transmission from remote area to onshore is obtained with the help of wireless transmission signal system called ZIGBEE. ZIGBEE is a wide range of signal which is used upto 1.6 miles, which is 160 times greater than bluetooth. Hence this transmission method is very useful to reduce the data transmission through the cable wires.

Brief description of universal gates

Logic gates are necessary in logic circuits. Logic circuits work only with logic inputs ( zero or one). Certain voltage levels are used to determine the logic inputs(LOW or HIGH). NAND and NOR gates are called universal gates.We can make all other logic gates using universal gates.

Linear integrated circuits in detail

An integrated circuit is a component called active. This is one component having a number of pins (two to several hundred), and that incorporates a number of components such as transistors, resistors, diodes, etc.. Some integrated circuits, such as NE555, has only a few tens of components, while others, such as microprocessors, can integrate several million. This article is about the integrated circuits in detail.

Buzzers and it's function

What is a buzzer? This article explains what a buzzer is in in-depth detail. You will get information about the types of buzzers and their functional uses.

GSM technology in Mobile communication system

Mobile communication is one of the fastest growing and demanding technologies in today’s world. GSM is the technology working behind mobile communications. The market is predicted to boom tremendously for the next 5 years in all four continents. China is the world’s biggest market. the Scope of this article is to provide information about GSM technology

Colour coding of resistor

In this article a brief and clear explanatinon is given about the method used in colour coding of resistors. It is simple and interesting. It is very much important to know the colour coding mehod to identify the value of resistor given by a manufacturer.Value of resistance can be found accurately using this method. Here explanation is given along with necessary listings and examples.

Importance of Operational amplifiers in electronics

An amplifier is a device that amplifies an input signal and produces the output with a large gain. The operational amplifiers can be considered as building blocks of many amplifiers. There are certain characteristics for a operational amplifiers. Here in this article a detailed view on operational amplifiers or op-amp is provided.

Wireless communication using RF

The information, medium of communication between two parties should be always kept secured. There are so many intruders in between who can Jam the information or retrieve the information. This project uses DSSS technology to avoid such scenario.

Analog Communication And Its Working

In this article, I am going to explain about the term 'Analog communication'. Also am going to explain about the operation and also its types. I have also added the points about some related terms like noise, transmitter, data etc.

How To Make Rectangular Microstrip Patch Antenna?

This project includes description, and simulation of Patch Antenna. Patch antenna basically a low cost, low profile and very efficient antenna that is frequently used in mobile and satellite communication . In order to stimulate patch antenna you will need a named IE3D.

Communication System And Communication Working

In this article, I have explained about the communication system and its working. I have first started it up with the history of the communication over the past decades and its present situation. I have also added some few terms related to the communication sector and also finally finished it with the need for the modulation.

Processor cycles and Acculmulator extensions

In this article, I have explained about the processor cycles, types of processor cycles and at last briefly stated about the accumulator and some of its extensions. I also explained about the machine cycle and the 7 basic cycles in it. I have also added the brief explanation of the terms such as RET and RSTn.

Signal Degradation and core cladding

In this article, I am going to explain about the term 'Signal Degradation'. It mainly referes the maximum repeaterless transmission between optical transmitter and receiver. It causes the optical pulses to strengthen as they travel along a fibre, the overlap between the passing puleses in the same channel, creating errors in the output and resulting in the problemsof information carrying capacity of the fibre.

LAPD Operations With Three Types Of Frames

LAPD plays a vital role behind the call establishment process. It has three major frames namely connection establishment, data transfer and disconnection. The following are the important abbrevations being used in the operation of LAPD. They are: SABME - Set Asynchronous Balance Mode Extended TEI - Terminal Environment Identifier SAPI - Service Access Point Identifier RR - Ready Receive RNR - Receive Not Ready

What is Intelligent information system (INS) and working of it?

Intelligent Information System uses the GSM technology for information transmission, it is interfaced with ARM processor to allow reliable information transfer as per programmed. Our project is based on ARM i.e., from designing of ARM PCB to its layout & component mountings. The main motto deals with transferring of information. Information is stored in the ARM processor and the receiver module is mobile handset. Thus information is transmitted from source to destination via GSM module.
