Identifying a Subset of a Function on a Graph Using LabVIEW

[Sanjay_C.]

Overview

This example explores how to define (and if need be extract) a section of a sine-wave.

Description
Analysis of a function often involves plotting the function, and in many cases, identifying critical points on a function. This example explores how to define (and if need be extract) a section of a sine-wave. For this example the goal is to identify any section(s) which represents a contiguous rise or fall from the value 4 to -4 in one full period of a sine wave of amplitude 5. This might be useful if we are interested in studying areas of the function which are moving quickly (since near the peaks and valleys of a sinusoid, the derivative drops off to zero).

Requirements
