Difference between Permittivity and Permeability
There are two physical quantities namely Permittivity and Permeability that play a vital role in the field electrical engineering. Permittivity is related to electrostatics and it is the measure of electrical polarization of a dielectric material when it is placed in an external electric field. Permeability is related to electromagnetism and it is the measure of magnetic polarization of a magnetic material when it is placed in an external magnetic field. In this article, we will highlight all the key differences between permittivity and permeability by considering different parameters like basic definition, unit, formula, importance, etc. Let's start ...

Read MoreDifference between Electromechanical Relay and Numerical Relay
In electric circuits, there is a device used to detect faulty conditions and protect the circuit from damages. It is known as relay. Thus, a relay can be defined as a device that identify faults and isolate the unhealth section of the circuit from the heathy system. In an electric circuit, a relay can provide protection against various types of faults like short-circuit, overcurrent, over-voltage, under-voltage, earth fault, and more. Overall, a relay is a protective device used to protect electric circuits from undesirable conditions, called faults. These protective relays can be classified in several types depending on their ...
Read MoreProperties of Convolution in Signals and Systems
ConvolutionConvolution is a mathematical tool for combining two signals to produce a third signal. In other words, the convolution can be defined as a mathematical operation that is used to express the relation between input and output an LTI system.Consider two signals $\mathit{x_{\mathrm{1}}\left( t\right )}$ and $\mathit{x_{\mathrm{2}}\left( t\right )}$. Then, the convolution of these two signals is defined as$$\mathrm{ \mathit{\mathit{y\left(t\right)=x_{\mathrm{1}}\left({t}\right)*x_{\mathrm{2}}\left({t}\right)\mathrm{=}\int_{-\infty }^{\infty }x_{\mathrm{1}}\left(\tau\right)x_{\mathrm{2}}\left(t-\tau\right)\:d\tau=\int_{-\infty }^{\infty }x_{\mathrm{2}}\left(\tau \right)x_{\mathrm{1}}\left(t-\tau\right)\:d\tau }}}$$Properties of ConvolutionContinuous-time convolution has basic and important properties, which are as follows −Commutative Property of Convolution − The commutative property of convolution states that the order in which we convolve two signals does not ...
