Peak Detector output Variation

[MKsarith]

Hi All...

I am facing some issues related with peak detector vi. Here I am attaching the Photo which describes the issue. From the peak detector vi, it is showing the peak amplitude which is more than the expected output. I have build an array with peak value as 5.3, and from the peak detector I am getting the peak amplitude as 5.93. how can I resove this?

Hi MK,

well, we could read the help for that VI:

Amplitudes contains the amplitudes of peaks or valleys found in the current block of data.

Note  The Locations and Amplitudes might deviate from actual peaks or valleys for noisy signals with large dynamic ranges.

And a little more down to the end of that text:

This Peak Detector VI is based on an algorithm that fits a quadratic polynomial to sequential groups of data points.
