One of the crucial difference between diode and thyristor is that a diode is a two terminal device used for rectification and switching applications. As against a thyristor is a three terminal device used for switching purpose. This generates the major difference in their operation. We know both diode and thyristor are semiconductor devices formed …
One major difference between star and ring topology is that in star topology the devices in the network are interconnected through a central hub. While in ring topology each device of the network is connected to its adjacent device present in the network. We know that topology refers to the way in which multiple devices …
FDM and TDM are the two types of multiplexing technique that allows simultaneous transmission of multiple signals over only one channel. One of the major difference between FDM and TDM is that in FDM, multiple signals are transmitted by occupying different frequency slots. As against in TDM, the various signal gets transmitted in multiple time …
The major difference between active and passive filter is that an active filter uses active components like transistor and op-amp for the filtering of electronic signals. As against, a passive filter uses passive components like resistor, inductor and capacitor to generate a signal of a particular band. Another major difference between the two is that …
Definition: In dual trace oscilloscope, a single electron beam generates 2 traces, that undergoes deflection by two independent sources. In order to produce two separate traces, basically, 2 methods are used, known as alternate and chopped mode. These are also known as the two operating modes of the switch. Now the question arises what is …
Definition: Graded Index fiber is another type of optical fiber in which the refractive index of the core is non-uniform. This non-uniformity is present because the refractive index is higher at the axis of the core and continuously reduces with the radial movement away from the axis. However, the refractive index of the cladding is …
Definition: Numerical Aperture is the measure of the ability of an optical fiber to collect or confine the incident light ray inside it. It is among the most basic property of optical fiber. Numerical aperture is abbreviated as NA and shows the efficiency with which light is collected inside the fiber in order to get …
Both optical fiber and coaxial cable are the types of guided media. But some major factors exist that differentiates the two. The crucial difference between optical fiber and coaxial cable is that an optical fiber is used for the transmission of the optical signal. As against, a coaxial cable is used for the transmission of …

Definition: Nd:YAG laser is the short form used for Neodymium-doped Yttrium Aluminium Garnet. It is a solid state and 4 level system as it consists of 4 energy levels. Nd ion is rare earth metal and it is doped with solid state host crystal like yttrium aluminium garnet (YAG – Y3Al5O12) to form Nd:YAG laser. …
Definition: An Optical Network is basically a communication network used for the exchange of information through an optical fiber cable between one end to another. It is one of the quickest networks used for data communication. As we already know that data signal through an optical fiber is transmitted in the form of light pulses. …
