Gain

Multiplies input signal by a constant gain factor.

Multiplies the input signal by a constant parameter k. The relationship between the input u and output y is simply y = k*u, where k is the gain factor. This block is useful for scaling signals or converting between different units.

This component extends from SISO

Usage

BlockComponents.Gain(k)

Parameters:

Name	Description	Units	Default value
k	Constant gain factor that multiplies the input signal	–

Connectors

• u - This connector represents a real signal as an input to a component (RealInput)

• y - This connector represents a real signal as an output from a component (RealOutput)

Behavior

$$\begin{array}{rl}y\left(t\right)& =ku\left(t\right)\end{array}$$
