Detect Slope Change of a Linear Signal in LabVIEW

[adlb]

Overview

Demonstrates how to locate the point(s) where a signal's slope changes.

Description

This example generates a simulated signal by creating a slope of 1 for first 50 and slope of 10 for the remainder. It then iterates through the Y data in 2's detecting slope and compares current slope to previous, if they are different, outputs the slope reading and location point(s) where the slope increases. In this example simulated signal data is generated and used, however, you could replace the simulated data with any other source, like from a spreadsheet, or from a driver like NI-DAQmx.

Requirements

LabVIEW 2013 (or compatible)

Steps to Implement or Execute Code

1. Run the program
2. The simulated signal will be displayed on a graph
3. The slope change point(s) and slope(s) will be indicated
