Sample rate problem with Output Block of DSP Builder

Altera_Forum · ‎12-10-2014

Hello

I have a sample rate problem with the Input or Output Block (sInOut S-function block) when I try to simulate my model in Matlab.

After this kind of block, it is always convert the sample rate of my signal to 1 second.

Here an example of my problem :

Here a part of my model, a put two scope : scope2 with an audio signal and scope1 with the signal after the Output Block.

An image of the Scope 2 with the Audio signal :

An image of the Scope 1 whith the signal after the Output Block.

As you can see, the sample rate was shrink to 1 second so I miss all the details of my signal.

How can I fix it ?

Thanks a lot for your help, I've working for hours on this problem.

I send you my entire project attached to this post.
