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.
Diversity Techniques Diversity is a good technique applied in mobile communication receiver circuits where there are multipath environments. The diversity techniques use the nature of the propagation path characteristics for…
Ground or Surface Wave A wave is said to be a ground wave or surface wave when it propagates from transmitter to receiver by gliding over the surface of the earth. This wave exists…
PhotoDiode Definition: A photodiode is a P-N junction that is operated under reverse bias and when exposed to light energy, the normal reverse current of the diode varies due to…
Radar Modulator Radar Modulator: A modulator is a heart in the transmitter. it not only controls the radiofrequency energy to be produced in sharp pulses but also controls the repetition…
Tunnel Diode Tunnel diode is a specially made p-n junction device which exhibits negative resistance over part of the forward bias characteristics. It has extremely heavy doping on both sides…
Facsimile Fax (short for facsimile, from Latin fac simile, “make similar”, i.e. “make a copy”) is a telecommunications technology used to transfer copies (facsimiles) of documents, especially using affordable devices…
Introduction to Number Systems Number System: A number is a collection of digits and it is represented by (N)b, where b is the base and N is the number. The…
Induction Motor Induction machines are also called asynchronous machines i.e., the machines which never run at a synchronous speed. Whenever we say induction machine we mean to say induction motor.…
Zener Diode The Zener diode is a normal PN junction diode. But it is different from PN junction on the basis of doping and also on working principle. When Zener…
Antenna What is an antenna? – An antenna is simply called a transducer, which converts radio frequency (RF) electrical current into electromagnetic (EM) waves at the same frequency and vice…
