Bias - Add bias to input

Library

Math Operations

Description

The Bias block adds a bias, or offset, to the input signal according to

where U is the block input and Y is the output.

Data Type Support

The Bias block accepts and outputs real or complex values of any numeric data type supported by Simulink software, except Boolean. The Bias block supports fixed-point data types.

For a discussion on the data types supported by Simulink software, see Data Types Supported by Simulink.

Parameters and Dialog Box

Bias

Specify the value of the offset to add to the input signal.

Saturate on integer overflow

If the input (and hence the output) is an integer data type (for example, int8) and the data type cannot accommodate the output signal, selecting this option causes the block to output the maximum value allowed by the data type. Otherwise, in this case, the block outputs the result of using twos-complement arithmetic to add the input to the output, i.e., the value is the result of adding the bias to the input modulo the maximum representable value of the data type.
