Re: [Seisunix] info derivative

Hi, I agree with you.

Comparing the outputs of suvibro f1=0.5 f2=0.5 | suxgraph style=normal width=1500 title=normal suvibro f1=0.5 f2=0.5 | suop of=diff | suxgraph style=normal width=1500 title=normal

it looks like there is an absolute value somewhere in the data flow. Notice that abs is the default option. So, I suspect a bug....

The code needs to be checked. D.

Hello everyone I would like to apply a derivative to a signal. I made a test with a simple cosine (created with suvibro) applying suop op=diff ... but I didn't get a sine. Why? thanks in advance -- luca
