PS Gain

Multiply input physical signal by constant

  • PS Gain block

Description

The PS Gain block performs element-wise multiplication of the input physical signal by a constant value (gain). You specify the gain as the Gain parameter value and unit.

The input signal value is multiplied by the value of the Gain parameter.

The signal unit at the output port is determined by unit propagation rules. For example, if the input signal is in N and the Gain parameter unit is m, then the output physical signal has the unit of N*m. For more information, see Physical Signal Unit Propagation.

Ports

Input

Input physical signal.

The port name is not visible in the block icon, but you can see this name in the underlying source file by clicking the Source code link in the Description tab of the block dialog box.

Output

Output physical signal.

The port name is not visible in the block icon, but you can see this name in the underlying source file by clicking the Source code link in the Description tab of the block dialog box.

Parameters

The multiplication coefficient. The first edit box represents the value of the coefficient. You can specify both positive and negative values.

The second combo box represents the unit of the multiplication coefficient. By default, the unit is 1 (unitless), which means that the output signal at port O has the same unit as the input signal. If you specify a different unit for the Gain parameter, then the signal unit at the output port O is the input signal unit multiplied by the unit of the Gain parameter. You can select a unit from the drop-down list or type the desired unit name, such as rpm, or a valid expression, such as rad/s. For more information and a list of unit abbreviations, see How to Specify Units in Block Dialogs and Unit Definitions.
