What is the difference between Laplace and Fourier and Z transforms?
Fourier transforms are for converting/representing a time-varying function in the frequency domain. Z-transforms are very similar to laplace but are discrete time-interval conversions, closer for digital implementations. They all appear the same because the methods used to convert are very similar.

What is z-transform and Laplace transform?
The Z-transform is used to analyse the discrete-time LTI (also called LSI - Linear Shift Invariant) systems. The Laplace transform is used to analyse the continuous-time LTI systems. The ZT converts the time-domain difference equations into the algebraic equations in z-domain.
What is Fourier and Laplace transformation?
The Laplace transform converts a signal to a complex plane. The Fourier transform transforms the same signal into the jw plane and is a subset of the Laplace transform in which the real part is 0. Answer. The Fourier transform can be used to smooth signals and interpolate functions.
What is z-transform and Fourier transform?
Z transform of sequence x(n) is given by. Fourier transform of sequence x(n) is given by. Complex variable z is expressed in polar form as Z= rejω where r= |z| and ω is ∟z. Thus we can be written as. Thus, X(z) can be interpreted as Fourier Transform of signal sequence (x(n) r–n).
