| Jun 11, 2015 at 20:11 | comment | added | John Alexiou | I added a test function in the post so you can check your results. | |

| Jun 11, 2015 at 20:05 | comment | added | RowanS | You have plotted incorrectly please double check. | |
| Jun 11, 2015 at 20:05 | comment | added | John Alexiou | I did plot and it is not correct. Please check your work before posting an answer. | |
| Jun 11, 2015 at 20:04 | comment | added | RowanS | What I have stated is correct. Plot it and you will see it's exactly what you want. | |
| Jun 11, 2015 at 20:03 | comment | added | John Alexiou | Based on what you stated a possible candinate is $$X_1+X_2 \cos((\omega_1-\omega_2) t+\varphi_1-\varphi_2) $$ | |
| Jun 11, 2015 at 20:01 | comment | added | John Alexiou | Getting closer, but the envelope angular frequency is $\omega_1-\omega_2$ or half of that. | |

| Jun 11, 2015 at 19:55 | comment | added | RowanS | $ envelope(t) =X_1+ X_2 \sin(\omega_2 t+\varphi_2) $ is the function you want then. Which satisfies the equations you wrote. You didn't say which sine wave was bigger | |
| Jun 11, 2015 at 19:47 | comment | added | John Alexiou | Nope, that is not it. The envelope function shouldn't cross zero. It should vary between $X_1+X_2$ and $|X_1-X_2|$ | |
