Transfer Fcn First Order

Implement discrete-time first order transfer function

Library

Discrete

Description

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.

Data Type Support

The Transfer Fcn First Order block accepts signals of the following data types:

  • Floating point

  • Built-in integer

  • Fixed point

For more information, see Data Types Supported by Simulink in the Simulink® documentation.

Parameters and Dialog Box

Pole (in Z plane)

Set the pole.

Initial condition for previous output

Set the initial condition for the previous output.

Integer rounding mode

Specify the rounding mode for fixed-point operations. For more information, see Rounding. in the Fixed-Point Designer™ documentation.

Saturate to max or min when overflows occur

Select to have overflows saturate to the maximum or minimum value that the data type can represent. Otherwise, overflows wrap.

When you select this check box, saturation applies to every internal operation on the block, not just the output or result. In general, the code generation process can detect when overflow is not possible. In this case, the code generator does not produce saturation code.

Characteristics

Direct Feedthrough

Yes

Scalar Expansion

Yes, of initial conditions

Zero-Crossing Detection

No
