[Act 3]

localDSP,you have requested for info related to my problem getting high spectrum values for Very Low Frequency values. Here is the info : The sampling frequency is 2 HZ (as required by HRV anlaysis), the measurement period is 300 seconds, and the window used is Hanning. I have the VI attached with this posting, and I hope to get an answer real soon.

Thanks.

Act,

Here is a link to that original posting that you and LocalDSP have been using.

Why am I getting very high values for the very low frequency region of a random signal?

By sticking with the one posting we can all keep the issue together, and other readers may be able to shed some light on the question for you."

Thanks Evan.
