 Overview

This example demonstrates how to amplitude modulates a carrier and message signal and generates a resultant modulated signal.

Graph Property Nodes are used to dynamically set the ranges of the Graphs to best suit the specified frequencies.

 
Requirements

  • LabVIEW 2012 (or compatible)


Steps to Implement or Execute Code

  1. Modify Carrier and Signal Frequency
  2. Run the program

figure 2figure 2figure 1figure 1Hello! Thanks for you vi.I test it measure modulated singal's frequency spectrum.But whether i try,it only shows one which is carrier frequency ,but in terms of AM theory ,it must three spectral lines,what happend?thanks ! And what's mean of figure 1and figure 2 big frame. Please!

 

ps: i use measure spectrum express vi to modulated singal.
