For FRD models, use the "delay2z" command to absorb delays into the frequency response without approximation.

The model is already discrete. For discrete models, the "pade" command maps all delays to poles at z=0.

The maximum approximation order is { ,number,integer} due to pole-zero cancellations.

The model order was increased to handle real negative poles.

The accuracy of discrete to continuous conversion using the "d2c" command may be poor.

The discrete to continuous conversion using the "d2c" command is only approximate due to internal delays. Check accuracy

Discretization is only approximate due to internal delays. Use faster sampling rate if discretization error is large

No explicit form exists for improper state-space models (models with infinite gain at s,z=Inf).
