Wave Analyzer

I’ve posted some new code under the projects section, a wave analyzer. It’s still pretty early in development, but you can use it to see how waves actually move, rather than just looking at formulas.

A simple sine wave is composed of 4 basic components: amplitude, frequency, wave length and phase angle. The wave analyzer allows you to add waves to the graph, and then tweak these components to see how it effects the output.

It gets interesting when you add multiple waves and then combine their output. This shows a similar output to what you would see if you had several wave generators hooked up to a string (in real life) and looked at their combined effect.

To get started, first go download the app (or source code). Run the application and then follow these steps to get something like this:



1. Click "Add Waveform"
2. Click "Add Waveform" again to get a second wave
3. Now in the Function Generators window, increase the wave
length parameter of the second wave.
4. You should now see the plot of two waves on the green
screen, to see the sum, click the "Sum All Channels"
button, on the main window
5. To see *just* the sum, go back toe the Function
Generators window and click the "visible" button on
both the waves to hide them
