What are the limitations of laplace transform?

Laplace will only generate an exact answer if initial conditions are provided


What is the difference between Fourier transform and Laplace transform and z transform?

Fourier transform and Laplace transform are similar. Laplace transforms map a function to a new function on the complex plane, while Fourier maps a function to a new function on the real line. You can view Fourier as the Laplace transform on the circle, that is |z|=1. z transform is the discrete version of Laplace transform.


What is relation between laplace transform and fourier transform?

The Laplace transform is related to the Fourier transform, but whereas the Fourier transform expresses a function or signal as a series of modes ofvibration (frequencies), the Laplace transform resolves a function into its moments. Like the Fourier transform, the Laplace transform is used for solving differential and integral equations.


Difference between z transform and laplace transform?

z transform is used for the digital signals and laplace is generally used of the contineous signals.


What is the difference between the fourier laplace transform?

They are similar. In many problems, both methods can be used. You can view Fourier transform is the Laplace transform on the circle, that is |z|=1. When you do Fourier transform, you don't need to worry about the convergence region. However, you need to find the convergence region for each Laplace transform. The discrete version of Fourier transform is discrete Fourier transform, and the discrete version of Laplace transform is Z-transform.


What kind of response is given by laplace transform analysis?

The type of response given by Laplace transform analysis is the frequency response.


Does every continious function has laplace transform?

There are continuous functions, for example f(t) = e^{t^2}, for which the integral defining the Laplace transform does not converge for any value of the Laplace variable s. So you could say that this continuous function does not have a Laplace transform.


Can a discontinuous function have a laplace transform?

Sure! The definition of Laplace transform involves the integral of a function, which always makes discontinuous continuous.


What mathematical process can you use to transform signal waveform of frequency domain into time domain. or the other way around?

This is called the Laplace transform and inverse Laplace transform.

How do you apply laplace transform method to solve systems of ordinary DEs?

you apply the Laplace transform on both sides of both equations. You will then get a sytem of algebraic equations which you can solve them simultaneously by purely algebraic methods. Then take the inverse Laplace transform .
