Delay the input by a certain number of samples. Positive delays insert zero items at the beginning of the stream. Negative delays discard items from the stream. You cannot initialize this block with a negative delay, however. That leads to a causality issue with the buffers when they are initialized. If you need to negatively delay one path, then put the positive delay on the other path instead.
Note that users have had issues when delaying by very large numbers.
Parameters
(R): Run-time adjustable
- Delay (R)
- Number of samples/items to delay by
Example Flowgraph
Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
