Why is z 1 delay?
polynomial by z-1 simply subtracts one from each exponent in the polynomial, thereby creating a delay of one.
What is the unit of delay element z '?
If z–transform of x(k) be X(z), then z–transform of x (k + 1) is zX (z). Therefore, for an input zX (z) to a delay element, output will be X(z). Hence the transfer function of delay element. We can also write the letter 'D' or z −1 in the block of 'unit delay' element.
What is the transfer function of unit delay?
In discrete-time models, a delay of one sampling period corresponds to a factor of z - 1 in the transfer function. For example, the following transfer function represents a discrete-time SISO system with a delay of 25 sampling periods. H ( z ) = z - 2 5 2 z - 0 .
