extracting multiple arrays from a 1D array

[s.steen]

I have an analoge signal of low voltage noise and square signals. I want to extract all square signals from the 1D array and put them in a 2D array. The distances between the square waves are not identical. That's why, I cannot divide the 1D array into multiple 1D arrays and search for numbers bigger than the range of the noise. I would be very thankful for any help!

do you have more info on the separation criteria?

i see that you have lots of 0.0627 and 0.1882 followed by one or more 0s

but then 5.0824 and 5.1451 without any 0s around it

the 5.0824 and 5.1451 without any 0s around it is the square wave. everythings else is noise. so I have the criteria that i want to extract all numbers that are, for example, bigger than 1. If I do that, i will have a 1D array of all of those numbers after eachother. I want to extract each square signal separately. the length of the square signal is not always similar. thank you.

Hi Sarah,

search for the beginning of each ">2.5" part/"signal", then search for the end of this part. Use ArraySubset to get the part. Put all this into a loop…

Do note that if your pulses are not the same length, your shorter pulses will be padded with 0 at the end when you change to a 2D array to keep all of the rows the same length.  But this code should do what you want.

my try, crossrulez beat me to it 😉

EDIT: fixed corner cases

Thank you very much for the reply!

Thank you so much for the codes!! I will try them!

What do u mean by the 2.5 part?

Hi Sarah,

it really helps when you write the name of the person you are asking instead of "u"…

The ">2.5" part is explained in crossrulz' snippet!
