Description

Adds two signals.

Example

Arithmetic Sum, difference, product, quotient, minimum, and maximum of a ramp and a constant.

a = tb = 2a + ba − ba · ba / bmin(a, b)max(a, b)

Ports

Inputs 2

  • +asignal

    First input, added.

  • +bsignal

    Second input, added.

Outputs 1

  • ysignal

    Output signal, a + b.

Equations

Modelica
y = a + b

Implementation
