There are many electronic circuits that are used for signal transmission. It can be an amplifier or modulator or it might be anything related to the signal strength enhancement. These devices are known for accepting the signal at a certain defined range of voltages. If the signal applied has an amplitude value greater than that of the range described this results in distortion or it may destroy the components present in the circuit. There is another problem related to signals that are their … [Read more...]
What is Nanotechnology : Types and Its Applications
Nowadays life without the use of nanotechnology is difficult to assume. This technology deals with nanomaterials and these are already existing in various products and it has a huge demand in the industrial sector. Nanotechnology is the term coined by a person named Norio Taniguchi in 1974. Usually, it is used for describing the processes in a semiconductor that is thin film deposition and to deal with the criterion on the scale of nanometers. The processes mainly included in nanotechnology are … [Read more...]
What are Nanomaterials : Properties & Their Applications
Nanotechnology is the most common term which deals with nanoscale materials. This technology is to make use of minute objects. The property of the materials changes when the bulk is split into small sizes. The nanoscale materials possess unique properties in the fields of electronic, optical or mechanical, etc...Even in ancient days, these materials are used as dyes in ceramics. The insulators at the molecular stages can behave as conductors at this nanoscale. The behavior of the nanomaterials … [Read more...]
What is a Splicing of Optical Fibers : Requirements & Its Techniques
Splicing of optical fibers is a fundamental method to connect two optical fibers permanently. Since the optical fibers are laid for long distances, which may even go up to hundreds of kilometers, it is not possible to lay a single line for such along with distance. Hence it becomes necessary to join two cables at certain points to increase the span of the cable. A lot of care is taken in splicing the fiber cables. It must be noted that, while joining the cables, no discontinuity should arrive in … [Read more...]
LED Scrolling Display Project Working With Circuit Diagram
We normally use a simple static LED display screen to convey a message. Earlier, when we want to display large data, we used to change message for every few instances. Now scrolling displays are more preferred to static. By using a pre programmed controller, we can make LED display in scrolling way. We can also make LED to adoptable by using PC controller based system. Simple Outdoor LED Message Moving or Scrolling Sign Board, Electronic projects using LED Scroller Generator for outdoor digital … [Read more...]
Block Diagram and Explanation of RF Transceivers
Generally, an RF module is a small size electronic device, that is used to transmit or receive radio signals between two devices. The main application of RF module is an embedded system to communicate with another device wirelessly. This communication may be accomplished through radio frequency communication. For various applications the medium of choice is radio frequency since it does not need line of sight. The applications of RF modules mainly involve in low volume and medium volume products … [Read more...]
Wireless Radio Frequency Technology Working and Applications
The term wireless RF stands for “wireless Radio Frequency Technology”. If you are just starting with radios, this article can help. It is proposed to give a basic understanding of radio frequency,as well work as a quick reference for those who “know their knowledge” but may be observed to brush up on that one place that they never quite understood. Radio frequency is a measurement signifying the oscillation rate of electromagnetic radio waves or electromagnetic radiation spectrum of frequencies … [Read more...]
Types Of Break Down Diodes And Applications
The break down diode is an electronic component with two electrodes called as the anode and the cathode. Most of the diode is made up of semiconductor materials such as silicon, germanium etc. The fundamental property of a diode is to conduct electric current in only one direction and blocks the current that flows in the opposite direction. When the cathode is negative charge related to the anode at a voltage greater than minimum called as forward breaker, then the current flows through the … [Read more...]
Development Process of Embedded Systems
Generally, in any kind of work, several tasks need to be done in the progression of meeting the purposes and goals intended at accomplishing through that effort. In addressing “what type of task need to be achieved”, numerous inputs and outputs and the complete contents of these tasks are defined and planned in a logical manner, which is jointly stated to as the “process”. In order to complete the expansion of software as a product, several types of tasks need to be achieved with layers like in … [Read more...]
What is a Ballistic Galvanometer : Construction & Its Working
A ballistic galvanometer is an instrument, which is used to measure or indicates current in a closed circuit. The galvanometer also is known as the PMMC instrument, works on the principle of permanent magnet moving coil. The force is generated on the coil, due to Lorentz Force Law. Due to the interaction of fluxes, the pointer in the meter is deflected. Once the pointer is deflected, different torques are exerted on the pointer to make the pointer stop at its steady-state position. The different … [Read more...]
