Reducing Classification

[Matteo14]

Hi,
I have 2 channels: ch1 and ch2. I want to build the trend of ch1 in function of ch2 and calculate, for different values of ch2, average, minimum, maximum and standard deviation of ch1.
I do the calculation of average, minimum and maximum through the Reducing Classification function. How can I calculate the standard deviation?
Many thanks
Matteo

Hi Matteo

I'd like to ask you to clarify what you mean by "build the trend of ch1 in function of ch2".  The reducing classification. reduces the effective sampling rate of an acquired signal by mapping N acquired data points onto 1 representative new data point, using the minimum, maximu, average, etc. to do that mapping.  Is that really what you're wanting to do?
