Max and Min of successive peaks having different amplitude

[dakudiv]

hello,

I have a signal having different values of successive Max and Minima.ie each Peak +/- is having different value.

I wanted to get successive +/-  peak values from the .CSV file.

I am done with the chart making from .csv file but, i am not able to get peak values please help.

What function should i use ??

How about Waveform Peak Detection?

Check it out. Heres where it is:
Programming >> Waveform >> Analog Waveform >> Waveform Measurements >> Waveform Monitoring

This will find both peaks and valleys (maxs and mins).

It will then output locations (x-value) and amplitue (y-value) of the point.

Hi,

Thanx a lot.

hi,

I was able to detect Peaks and Valley's.

But if there is some distortion at the ends of the signal it detects them as two peaks.I tried inceasing the wodth but it did not helped.

Please Suggest a method.

Thanx and Regards

Hi,

I am able to get the graph , and i linked both the files to get the maxima and minima.

But i am not able to get the Grid behid the graph.

Please see attached diag.

I'm not on my computer with LabVIEW , so I can double check this for you Monday.

However, I'm going to try this from memory.

Right click either the x or y axis.

There should be some kind of option that can set to make a grid, and on either major ticks, minor ticks, or both.

you can select this for both x or y scale.

This is port of the scales property of the graph.

• Right-click the graph.
• select "properties".
• select the "scales" tab.
• Check the lower left corner for the grid style/grid color.
• (repeat by selecting the other scale in the upper left of the same tab).
