delaynumdelayden
Delaynumdelayden is not a standard term in most references. In wiki-style usage it can be described as the operation of applying separate time-delay operators to the numerator and the denominator of a rational transfer function, often to model or adjust delays in a system.
Concept and mathematical basis
For a discrete-time transfer function G(z) = N(z) / D(z), where N(z) and D(z) are polynomials in z^-1,
The operation is mainly a theoretical or modeling tool: it helps to align dynamic elements or to
Delaynumdelayden relates to broader topics such as time-delay modeling, z-transform manipulations, and Padé approximations used to
Time delay, z-transform, discrete-time systems, continuous-time transfer functions, Padé approximation.
