Casing Capping Wiring

This is one of the simple forms of electric wiring systems . This is little bit old/conventional wiring system. Now days we very often use this cashing capping electric wiring system . As the name referred in this wiring, PVC insulated wires are placed in plastic cashing and covered with cap. The ca

System of Electrical Wiring

What is Electrical Wiring? Electrical wiring is the electrical power distribution through the wires in a perfect manner for economic use of wiring conductors inside a room or building with better load control. Electrical wiring system is classified into five categories: Cleat wiring Casing wiring Ba

Trigonometric Fourier Series

We have already discussed the Fourier series in exponential form. In this article we will discuss another form of Fourier series i.e. Trigonometric Fourier series . Fourier series representation in Trigonometric form Fourier series in trigonometric form can be easily derived from its exponential for

Analysis of Exponential Fourier Series

Fourier Series at a Glance A continuous time signal x(t) is said to be periodic if there is a positive non-zero value of T for which As we know any periodic signal can be classified into harmonically related sinusoids or complex exponential, provided it satisfies the Dirichlet’s Conditions . This de

Fourier Series and Fourier Transform

Sometimes all the information in time domain is not sufficient. This makes us to move to frequency domain of the signal for extracting more information about the signal. This movement from one domain to other domain is known as transformation. For changing the domain of signal from time to frequency

Time Domain Analysis of Control System

In a control system , there may be some energy storing elements attached to it. Energy storing elements are generally inductors and capacitors in case of an electrical system. Due to the presence of these energy storing elements, if the energy state of the system is disturbed, it will take a certain

Nichols Chart: What is it?

What is a Nichols Chart? A Nichols Chart (also known as a Nichols Plot) is a plot used in signal processing and control system design to determine the stability and closed-loop frequency response of a feedback system. The Nichols chart is named after its founder, Nathaniel B. Nichols . How Does A Ni

Laplace Transform Table, Formula, Examples & Properties

Laplace transformation is a technique for solving differential equations. Here differential equation of time domain form is first transformed to algebraic equation of frequency domain form. After solving the algebraic equation in frequency domain, the result then is finally transformed to time domai

Nyquist Plot: What is it? (And How To Draw One)

What is a Nyquist Plot? A Nyquist plot (or Nyquist Diagram ) is a frequency response plot used in control engineering and signal processing . Nyquist plots are commonly used to assess the stability of a control system with feedback. In Cartesian coordinates, the real part of the transfer function is

Transfer Function of Control System

A transfer function represents the relationship between the output signal of a control system and the input signal, for all possible input values. A block diagram is a visualization of the control system which uses blocks to represent the transfer function, and arrows which represent the various inp

Final Value Theorem in Laplace Transform (Proof & Examples)

In the solution of Networks, Transient, and Systems sometimes we may not be interested in finding out the entire function of time f(t) from it’s Laplace Transform F(s), which is available for the solution. It is very interesting to find that we can find the first value or last value of f(t) or it’s

Initial Value Theorem of Laplace Transform

Initial Value Theorem is one of the basic properties of Laplace transform . It was given by prominent French Mathematical Physicist Pierre Simon Marquis De Laplace. He made crucial contributions in the area of planetary motion by applying Newton’s theory of Gravitation. His work regarding the theory
