When enabled (default), this block copies its input to its output. When disabled, this block drops its input on the floor.
Parameters
(R): Run-time adjustable
- Type
-
- Complex
- Float

Example Flowgraph
The following graph depicts the usage of the copy block.
Initially, copy is enabled, so the data is transferred to the output of the copy block.
But when the block receives the msg of pmt.from_bool(False) after 2.5 seconds, it starts dropping all of the upcoming data.
