intensity graph segments

Hello 

 

I am having a 2D complex array . I would like to plot the 'r' values to an intensity graph. I have plotted it but am getting some kind of overlays..See attachment. Can anyone say why is it so?

Those intensity changes are in your data.

First, I changed your chart with a graph for my own clearity.

Because the values are hard to work with, I normalized them (subtract min,
devide by max-min).

I also changed the Time scale's multiplier from 1.8 to 1. Again, just for
clearity.

Then I looked at the r array, and compared the values at the weird looking
places with. At element 63, the value is 0.21, at element 64 it is 0.42. No
wonder you see an intensity change! In the original, at element 63, the
value is 1.1E9, at element 64 it is 2.2E9.

Regards,

Wiebe.

Hello Wiebe

 

Thankyou very much. Then I think something is wrong with my 2D array. I have to check it once more...I get that 2D array after performing a kind of transformation on an image.somethin might b wrong there.

 

In the theoritcial result of the above VI, the result does not contain any such changes in intensity.That is why i asked.

 

Thanks

Looking at the data, I see that the "high frequency" data (the least
significant data) continues, but the "low frequency" (the most significant
data) seems to make steps. Sound to me like an overflow of an integer or a
phase jumping from 359 to 0 or something like it...

Regards,

Wiebe.

Hello Wiebe


Yes . these values are complex numbers whose phase varies from 0 to 360 degrees. Now i understood.
