Transfer Fcn Real Zero - Implement discrete-time transfer function that has real zero and no pole

Library

Discrete

Description

The Transfer Fcn Real Zero block implements a discrete-time transfer function that has a real zero and effectively has no pole.

Data Type Support

The Transfer Fcn Real Zero block accepts signals of any numeric data type supported by Simulink software, including fixed-point data types.

Parameters and Dialog Box

Zero (in Z plane)

Set the zero.

Initial condition for previous input

Set the initial condition for the previous input.

Integer rounding mode

Specify the rounding mode for fixed-point operations. For more information, see Rounding in the Simulink Fixed Point User's Guide.

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
