Eq (3.54): X(z) = sum_n x(n) z^-n; eq (3.55) is the causal FIR case

A step of the rangayyan_xfrm implementation. Called by Zfm. See the file header for the source the module follows. the source it follows.

Usage

Ztrans(x, z = NULL, n0 = 0)

Arguments

x

Coerced to numeric by the body, with as.numeric.

z

Optional; may be NULL. Coerced to complex by the body, with as.complex.

n0

Numeric; combined arithmetically in the body. Defaults to 0.

Value

The value of out, as built in the body.

Examples

V <- c(1, 2, 3, 4, 5, 6, 7, 8)
