I need to clip or make my signal flat at local maximas.
e.g if I get a local maxima at 5,1,7,8,4 then want to cut this local maxima let’s suppose to (pks-1) and plot it means it will plot the signal at 4,0,6,7,3 but with flat curve.
Similarly I want to try this for different combinations like (pks-0.4) or in short Range from (0.2 ----1.3) and make plots .Range can be provided by putting loops.
I remained unable to provide here an example using MATLAB because I am confused in it so just attaching a picture to get an idea or overview.
Example code for finding Maximas:
t = 1:25 ;
A = [1 0 1 2 3 5 0 1 0 0 0 2 3 6 7 0 0 8 0 1 1 2 3 4 2];
[pks,locs] = findpeaks(A)
Sorry NO idea about how to clip at maximas I tried but the code is not so mature so i remained unable to provide it here.
Dear Asif,
welcome!
The sequence you gave an example contains only integer values, so if you want to clip at peaks- 1, it works because you find this level in the your sequence.
If you want to clip at peaks- decimal fraction for example 0.2, then you can not find such level in your sequence since it does not contain for example 5-0.2= 4.8. So, you have to interpolate you sequence. As an example you double your points in the series from 25 to 49 by inserting additional values in the series: Ainterpolated=( 1, .5,0, .5,1,1.5,..........,4,3,2). You can interpolate by 3 where you can insert two intermediate points between every two points in the original series. And so on by 4 or 5 as fine as desire. After that when you search you find the intended clipping level or a close approximation to it. That is you will find a solution.
