how to find number of crossings of a signal above a thershold.

vamshiky over 10 years ago

HI,

I tried using cross function to get all crossing but now need the count for these crossings.

length( cross(...) ) failed to evaluate.

Thanks,

Vamshi

Hi Vamshi,

cross() returns a waveform, so length will not work. You need to convert it to a vector and then get the vector length. Try:

drVectorLength(drGetWaveformYVec(cross...))

Regards,

TOM

If the crossing number is passed as 0, it should return a list of the crossings rather than a waveform. What precise arguments did you give to the cross function? Regards, Andrew.

Thanks for the reply Andrew, it works now.

Earlier I tried using 'No. of occurences' as multiple and so it failed to evaluate.

@TOM, Thanks your solution also works.
