Hi,

You can use Scifunc block.
You can find an example at
http://www.scicos.org/examples.html (Signal Processing Application)

You must install a recent version of Scilab (Scilab 3.0 or above).

Hi,
You need a C compiler because the example uses CBlock2 block, although
fft is done by Scifunc block.
If you don't have a C compiler,

scicos buffer.cos

command will crash with error message and you won't see the block
diagram.
