Trying To Add Sine Waves
-
I am looking for a website which will allow me to add sine waves. Can someone tell me what question to ask Google ? I know several questions that ***don't*** work. I want to... - Input the frequency - Input the phase angle - Input the amplitude (nice to have, not required) - Click on a button - See the resulting wave form (save as PNG or whatever would be nice) These phrases and questions don't work... - *free online graphing tool to add two sine waves together - online graph, adding two sine waves together - add two sine waves together - add two sound waves together - Add two frequencies - Online Tone generator* Certainly I'm not the only guy on the internet who has ever wanted this. What question do I ask ? How do I phrase it ?

This do it? Wave Adder[^] My Google query was "how to add waves graphically" and it was the 6th link.

Nice catch. Thank you and you are voted up My physics is messed up. If I add two sine waves, same amplitude, same frequency, but off by 180 degrees, I'm supposed to get zero. Wave Adder gives me a much lower amplitude, but not zero. Am I missing something ? Maybe congress changed the laws of physics.

Will you check my numbers ? I just did... - Amplitude 7 - Frequency 3 - Phase (zero, then 180) The two graphs are not 180 degrees out of phase; looks like about 10 degrees.

Radians, not degrees, I think: try 3.1415

Wikipedia:
In general, mathematically important relationships between the sine and cosine functions and the exponential function (see, for example, Euler's formula) are substantially simplified when angles are expressed in radians, rather than in degrees, grads or other units. Therefore, in most branches of mathematics beyond practical geometry, angles are generally assumed to be expressed in radians.
And that's the case in .NET or JavaScript and Java and PHP too...All except radians and not degrees...

Strangely, neither. 360° ^= 2.06 or something thereabouts.

Yes, now that I've learned how to click the "pi" button on Microsoft Calc, I'm home free.

Looks like there's something weird going on with frequency and phase shift: Take 3.1415 as phase shift and then look at the graphs for the frequencies 1 and 2.. That 2.06 value I got with a frequency of 3: Look at phase shifts 0, 0.5, 1, 1.5, 2.06 ..

IMHO, having the words - 'superpose', 'superposition' - may yield better results.

It looks fine for me: 2.06 radians as a phase shift with a frequency of 3 looks about right given that
3 * (2.06 / 2) = 3.09 ~= π

360 degrees is just for the stupid humans since we like whole numbers. Non-rational numbers aren't so nice for us. Pi is a number to describe the relations in a circle, and it is basically how Sinus and Cosinus are defined.

If you have problems finding this on google, you might just as well create a program that does it :D
