Somebody knows how is possible to find frequency and amplitude for the
most important waves of a primary wave with no complicated
calculation? I need to find at max the first five subwaves. In anyway
there is in the web a software or a site that do that?
If it can help you i attach the primary wave data below. I need
frequency and amplitude of the first five subwaves
