Description

The RelationalOp block compares two input signals defined by the relational operator (parameter).

Supported relational operations are : "==", "~=", "<", "<=", ">" and ">=".

if the operator is "==", the result is TRUE if the two inputs are equal.

if the operator is "~=", the result is TRUE if the two inputs are not equal.

if the operator is "<", the result is TRUE if the first input is less than the second input.

if the operator is "<=", the result is TRUE if the first input is less or equal than the second input.

if the operator is ">", the result is TRUE if the first input is greater than the second input.

if the operator is ">=", the result is TRUE if the first input is greater or equal than the second input.
