How do you find the z-transform of a signal in Matlab?
ztrans( f ) finds the Z-Transform of f . By default, the independent variable is n and the transformation variable is z . If f does not contain n , ztrans uses symvar . ztrans( f , transVar ) uses the transformation variable transVar instead of z .
When z-transform of a discrete-time signal?
In mathematics and signal processing, the Z-transform converts a discrete-time signal, which is a sequence of real or complex numbers, into a complex frequency-domain (z-domain or z-plane) representation. It can be considered as a discrete-time equivalent of the Laplace transform (s-domain).
How do you find the z-transform of a delta function?
So if we have x(n)=δ(n)+δ(n−1) the transform should look like X(z)=∑(δ(n)+δ(n−1))z−n with the sum going to infinity.
