Discrete

The Transfer Fcn First Order block implements a discrete-time first order transfer function of the input. The transfer function has a unity DC gain.
The Transfer Fcn First Order block accepts signals of any numeric data type supported by Simulink software, including fixed-point data types.

Set the pole.
Set the initial condition for the previous output.
Select the rounding mode for fixed-point operations. For more information, see Rounding in the Simulink Fixed Point User's Guide.
If selected, fixed-point overflows saturate.
Direct Feedthrough | Yes |
Scalar Expansion | Yes, of initial conditions |
