Hi,
For educational purposes I try to use gnuradio to realize simple digital filters with delay, add and multiply blocks.
This is perfect for non-recursive filters but it does not seem possible to make loops as in the example above and thus impossible to build a recursive filter on the same principle?
Thanks

Thomas

Loops are strictly forbidden by the buffer-management model.

However, you can loop *internally* within a block.
