Z Transform Primer

Z Transform Primer

Z Transform Primer. Basic Concepts. Consider a sequence of values: {x k : k = 0,1,2,... } These may be samples of a function x(t), sampled at instants t = kT; thus x k = x(kT). The Z transform is simply a polynomial in z having the x k as coefficients:. Fundamental Functions.

Optical Transfer Function

Optical Transfer Function

Optical Transfer Function. Optical transfer function (OTF) Fourier transform of the PSF function characterizes frequencies transmitted by the optical system in real optical systems OTF domain is finite (image is band-limited ) the largest transmitted frequency is called cut-off frequency.
