enter image description hereI generate a graph using X and Y column of data (its time vs voltage graph X represent time and Y represent voltage column)

Need to work To calculate quarter of in one period of cycle. (place marker for better representation)

So I am looking some algo/Mathmatics input which can give some direction

If I map my work, this below url provide info about period and amplitude of the waveform But They have equation

https://www.mathsisfun.com/algebra/amplitude-period-frequency-phase-shift.html

In a similar way, I need to calculate amplitude in one cycle. How should I convert data point to the equation.

Input. similiar I have 1000 points.

  • Your function is not a sine or a cosine, so it doesn't make sense to "convert data point to the equation" with the equation as given – Ben Grossmann Aug 20 '20 at 09:31
  • As for the problem of determining amplitude and period, that is more a programming problem than a mathematics problem. What software are you using for this data? – Ben Grossmann Aug 20 '20 at 09:33
  • I am looking some mathmatics function which can do similiar thing. Programming I will take care. I am not using any software and placing plot using matplotlib – user765443 Aug 20 '20 at 09:50
  • What exactly would you call "matplotlib" if not software? in any case, please clarify what you mean by "some mathmatics function which can do similiar thing". – Ben Grossmann Aug 20 '20 at 09:52
  • I mean, can we determine solve problem through mathmatics if we have data point is X and Y. Determine one cycle. Determine ampliture – user765443 Aug 20 '20 at 09:54
  • I saw some post which convert data point to equation so idea come in my mind but as of now totally blank – user765443 Aug 20 '20 at 09:55
  • Let us continue this discussion in chat. – user765443 Aug 20 '20 at 10:16
  • I think I am stupid, what about this, if store start point of Y axis and repeat again than it is hlaf cycle. than if determine x-point than take half value it will solve my purpose – user765443 Aug 20 '20 at 10:20
