Domains: Discrete, Continuous. Size: 1-D. Allowed in: Block Diagrams.

Implementations

This block has 8 implementations varying from a 2-input OR to a 9-input OR.

inputs_2
inputs_3
inputs_4
inputs_5
inputs_6
inputs_7
inputs_8
inputs_9

Description

The output signal of this submodel for the two-input OR is according the truth table below:

 

input1

input2

output

false

false

false

false

true

true

true

false

true

true

true

true

 

The output signal for the other OR implementations follows a similar pattern. The output signal is only false when all input signals are equal to false.

Restrictions

This block operates with boolean inputs. Real of integer inputs can also be used but will lead to a warning during processing. Be careful with using real or integer inputs: A value of 0.0 is converted to false, any other value is converted to true.
