Electronics Club website is a place for any student or people, those are interested to know about the basic ideas of Electronics and Communication Engineering.
Comparison between Hydraulic and Pneumatic Systems In this post, the Comparison between Hydraulic and Pneumatic Systems is given in the tabular form. But before the table learns some basic definitions,…
Transmission Losses Various types of optical signal transmission losses in optical fiber cables result in less output power than required, thereby reducing the overall system capacity, net transmission bandwidth, transmission…
Stepper Motor A special type of synchronous motor designed to rotate through a specific angle for each electrical pulse applied is known as a stepper motor. The specific angle through…
Kepler’s Laws of planetary motion Kepler’s laws apply quite generally to any two bodies in space that interact through gravitation. The more massive of the two bodies is referred to…
Gate Turn Off (G.T.O.) Thyristor Gate Turn Off (G.T.O.) Thyristor: A gate turn-off thyristor, a pnpn device, can be turned on like an ordinary thyristor by a pulse of positive…
Servomotor Servomotor: The servomotors are used to convert an electrical signal (control voltage) applied to them into an angular displacement of the shaft. They are normally coupled to the controlled…
Erbium-Doped Fiber Amplifiers (EDFAs) Erbium-doped fiber amplifiers (EDFAs) make use of rare-earth elements such as erbium (Er3+) as amplification medium. It is doped into the fiber core during the manufacturing…
Raman fiber amplifier (RFA) A Raman fiber amplifier (RFA) is based on an intrinsic non-linearity present in the form of a stimulated Raman scattering (SRS) mechanism. When a high-power optical…
Semiconductor Optical Amplifiers (SOA) A semiconductor optical amplifier (SOA), also known as a laser amplifier, is an active medium of a semiconductor laser. In other words, an SOA is a…
Insulated Gate Bipolar Transistor (IGBT) There are numerous types of power semiconductor switches and among these switches, the insulated gate bipolar transistor (1GBT), which combines some of the features of…
