What is the convolution property of Z-transform?
The convolution property of the Z Transform makes it convenient to obtain the Z Transform for the convolution of two sequences as the product of their respective Z Transforms.
What is the time shifting property of Z-transform?
Time Shifting: If we have a time-shifted sequence such as x[n-k], then its z-transform is given by Z x[n-k] = z^-kX(z). Let's take n – k = m, i.e., n = k + m and y[n] = x[n-k].
