How to find out the sampling frequenz

[Hasiman]

Hello,

is it possible to find out the sampling frequenz. I've got a incoming signal that I low- and highpassed (0,5-4Hz) with a 88Hz sampling frequenz.

Now I want to get the time between 2 points/peaks/valleys. To do this succesfully, I need to know the sample rate. How can I find this out?

Hi hasiman,

I've got a incoming signal

You should know the source of this signal and so you should know it's sampling frequency!

(And so you should know more than we could read from your post…)

Hello Gerd,

I have got the ADC LTC2440.

The SDI Pin is on ground, so the output Rate is 880Hz. But I do not think that's my sample rate 😕

I filtered with fs=88Hz, so I sample the output data with 88Hz ?

Hi hasiman,

I still don't know how you read your samples...

You should be able to determine the sample rate in your VI - at the place where you actually read the samples!
