Dear All,

I use the NR convlv() function in my ANSI C program.
I have a signal array, and a response array like this:

signal[1024];
response[1024];

convlv(signal, 1024, resp, 307, +1, ans);

And I get the convolved result in the first half of
ans[2048];


The filesare attached(ASCII):
signal-prog-txt
response-prog-txt
signal-convolved-txt

And this result looks fine.

Now, I want to get back the original signal, by deconvolving the
convolved one with the response signal:

convlv(signal-convolved, 1024, resp, 307, -1, ans);

And now what I get is a mess:
signal-deconvolved-txt


, i do not get back the original signal. I do something wrong, but no clue how...:confused:
Someone please could help me?
Thank you very much,
Best Regards:),

There was a little mistypeing, sorry for silly question. The code just works fine! :)
beginner's fault :D
