Homework Help: Simulation of beats

  1. Dec 11, 2005 #1
    I am working on creating a simulation of beats. I need to start with:

    (where w is angular frequency),

    w1 + w2 = w1,2
    then
    w1,2 + w3 = w1,2,3
    then
    w1,2,3 + w4 = w1,2,3,4
    and so on, to create a wave packet where I will plot w1,2,3,4...n.

    My problem is that I do not understand how to add the angular frequencies in order to arrive at the resultant frequencies! I have only found equations for amplitude displacement of the sound wave, nothing about adding angular frequencies. And I know that I am not supposed to find the beat frequency.

    Any help pointing me in the right direction would be appreciated. Thank you!

    I don't understand what you are trying to do. Can you elaborate?
