Extract values from waveform

[test_man]

How do I extract following values from attached waveform?

1. Normal peak value/Most common peak value. In sample waveform  it is around 0.21V

2. Spike value/Some peak values. In sample waveform  it is around 0.28V.

I can use array max function get 0.28 spike value but sometimes my spike values are very close to my normal peak values. For example spike value is 0.235. In this case I wouldn't know if 0.235 is normal peak or spike. First I have to find normal peak value and then use that number to find spike values if any spike is there.

I have attached sample waveform data vi.

Hi Test man,

I recommend taking a look at the peak detection examples that ship with LabVIEW. You may also consider once you have identified the largest peak, you can remove it from the waveforma dn then calculate the average of the other peaks.

Let me know if you have any questions or more details.
