Feedback
The feedback algorithm generates a delay in the signal path and reroutes signal to an input occurring earlier in the path. Note that this block must be used if feedback is required in your design. The standard delay block cannot be used to create feedback systems.
There are two versions of ' Feedback' algorithm.
- Feedback(Sample)
- Feedback(Block)
Feedback(Sample)
Generates one sample delay in the signal path and reroutes the signal to an input occurring earlier in the path.
Feedback(Block)
Generates delay equal to one blocksize in the signal path and reroutes the signal to an input occurring earlier in the path.
