| Jan 28, 2015 at 19:11 | comment | added | stuffu | It is possible to find more than one frequency in the basic vibration by doing a Fourier transform of the basic vibration. But if we believe the Fourier transform then there are no amplitude changes. Fourier transform does not acknowledge existence of any amplitude changes. So if we want that there are beats we say that there is just one frequency whose amplitude is changing, even if it would be possible to say that there are two frequencies whose amplitudes are not changing. | |

| Jan 28, 2015 at 14:48 | comment | added | stuffu | With "constant amplitude" author is referring to slowly changing amplitude. Seriously. I am not misunderstanding the author. Slowly changing amplitude approximates constant amplitude. What is "basic vibration"? Beats are amplitude changes, basic vibration is the vibration whose amplitude changes. Author says that putting two waves together results one wave whose frequency is the average of the frequencies of the original waves, and that wave the author calls "basic vibration". | |

| Jan 28, 2015 at 12:37 | comment | added | user36790 | Sir,can you tell why the author mentioned about constant amplitude? Beat has no constant amplitude,right? Please help what the author wanted to tell. | |
