Antenna Definition: The Antenna Definition is a quick review of impedance matching (basic transformer theory) and resonant circuits. It was pointed out that maximum power transfer could be achieved only…
Radiation and Propagation of Waves Articles: Fundamentals of Electromagnetic Waves: Fundamentals of Electromagnetic Waves are energy propagated through free space at the velocity of light, which is approximately 300 meters…
Extraterrestrial Communications: Extraterrestrial Communications : The most recent, and by far the fastest-growing, field of communications involves the use of various satellite relays, of which the first was launched in…
Refraction of Waves: As with light, Refraction of Waves takes place when electromagnetic waves pass from one propagating medium to a medium having a different density. This situation causes the…
Reflection of Waves: There is much similarity between the reflection of light by a mirror and the reflection of electromagnetic waves by a conducting medium. In both instances the angle…
Interfacing with Microprocessors Articles: BCD to 7 Segment Decoder using IC 7447: BCD to 7 Segment Decoder using IC 7447 are generally used as numerical indicators and consists of a…
Sensors and Transducers: The definition of Sensors and Transducers are follows, The input quantity for most instrumentation systems is nonelectrical. In order to use electrical methods and techniques for measurement, the…
Solid State Relay Interfacing: To avoid the problems of mechanical relays, Solid State Relay Interfacing are used. In this triac is used as a switching element and isolation is provided…
