What is Hooke’s Law | Definition Formula

Hooke’s Law Introduction There are many examples of things that oscillate. Oscillations refer to an object or system that moves back and forth between two points and creates waves.  A guitar string vibrates back and forth when plucked; the oscillations of the cone inside an audio speaker makes it produce …

Difference between Electric field and Magnetic Field

An Electric field takes place where a voltage exists. They are produced around appliances and cables since a voltage exists. If the voltage is higher, an electric field is stronger and its strength is measured in volts per meter (V/m). The field strength diminishes quickly as we move away from …

Difference between DC Motor and DC Generator

DC motor and DC generator are similar from the mechanical perspective, however from a technical stand point, both differ from each other significantly. The most significant difference between DC motor and DC generator lies in the conversion mechanism. DC motor converts electrical energy into mechanical energy whereas DC generator converts …

Effect of Zeros on System Response

The zeros zj of G(s) do not affect the system stability. However, they do affect the amplitudes of the mode functions in the system response and can block the transmission of certain input signals. In general, to assess the Impact of the zeros on the amplitude of the mode functions, …

Zero State Response using Matlab

Response to a General Input In addition to computing and plotting the impulse and step responses of a system, MATLAB can be used to find and display the response to general functions of time. This is done with the lsim command, which can be used in a variety of ways. …

Impulse Response using Matlab

Impulse Response using Matlab

How to Obtain an Impulse Response Once a transform (or transfer function) G(s) has been defined in MATLAB, operations can be performed to compute and display the corresponding time function g(t), known as the inverse Laplace transform. If the poles are known, G(s) can be written as a partial-fraction expansion …
