Detect rising edge when signal's value increases to strictly positive value, and its previous value was nonpositive

Library

Logic and Bit Operations

Description

The Detect Rise Positive block determines if the input is strictly positive, and its previous value was nonpositive where

The output is true (equal to 1), when the input signal is greater than zero, and its previous value was less than zero.
The output is false (equal to 0), when the input is negative or zero, or if the input is positive, its previous value was also positive.

Data Type Support

The Detect Rise Positive block accepts signals of any data type supported by Simulink^® software, including fixed-point data types. The block output is uint8.

Parameters and Dialog Box

Initial condition: Set the initial condition of the Boolean expression U/z > 0.
