Blocks the DC component of a signal. This can be useful when working with AM signals, as taking the magnitude of the envelope will always be positive and thus introduce a DC bias on the signal.


Specifies the length of the delay line used for determining the DC level. Only applicable to the long form.
Long Form
When set to True, use the long form DC blocker, with delay line. When set to False, use the short form (faster).

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.
