In our day-to-day life we frequently got used to listen the news, music and other programs through FM radio station by tuning to our favorite bands with wireless transmission and reception of data. Edwin Armstrong developed super-regenerative circuits and super-heterodyne receiver, which made radio broadcasting successful. In 1933, a revolutionary change was made by Armstrong in the broadcasting business with FM radio. The entire system depends on the FM radio transmitter to transmit the data from the transmitter end to the receiver end. But, are you aware of working of these FM transmitter and receiver circuits?

For improving productivity and the quality of end products, most of the industries are equipped with advanced control systems by adopting complex control strategies for both critical and non-critical applications.
These modern industrial control systems are usually made to produce one or more control actions depending on the application implemented. This article describes the basic control strategies used in industrial control system and its types with a brief explanation. [Read more…]
Nowadays home automation system is an emerging technology that operates the electrical appliances and loads remotely by using advanced controllers with proponent communication technology. This is an advancement of the conventional mechanization process wherein human efforts are needed to operate the electrical devices or appliances . Control capability is more sophisticated with this automation ranging from low level to high level control. So let us look at this topic in brief with practical examples. [Read more…]
The passive two terminal electrical components that resist the flow of electrical current in an electrical network can be termed as Resistor. Resistors can be used for controlling or reducing the voltage levels within a circuit, and the voltage across an element in a circuit can be determined by the voltage drop across the resistor in parallel to that element. Resistors are of fixed or variable resistances, viz. photoresistor, humistors, varistors, trimmers, thermistors and potentiometers. Resistors are classified into different types based on different properties.

A location-based service (LBS) is a software application for a IP-capable mobile device that requires knowledge about where the mobile device is located. Location-based services play an important role in the future applications of satellite navigation. Location based services (LBS) are services offered through a mobile phone and take into account the device’s geographical location. [Read more…]
The execution of projects is an essential task for technical students as they pursue their studies. During the course of their engineering studies, projects help them to gain some practical knowledge from their studies. Many companies ask students about the projects they have developed to test their skills and knowledge. [Read more…]
Some critical applications need temporary hold off supply voltage for the backup supply kicks especially the applications like power meters, power electronic drives and industrial or home alarm systems. Therefore, the LTC 3355 voltage regulator IC supplies momentary uninterrupted power to the device from the energy stored in the capacitor and also it produces regulated power. It thus reduces the need to replace a battery and minimizes the maintenance of portable backup systems and low-cost applications. This article provides a brief description about this IC pin, its configuration, and operation. [Read more…]
In this core competent world, one must equip or empower oneself with some specific skills and abilities to be independent and expert in a certain specified field. There is a significant difference between understanding a project by theory or flow of information and managing the project itself, but one should know the information before implementing the project. Therefore, practical knowledge is the most essential criterion for successful evaluation of the electronic projects. [Read more…]
