A source of zeros used mainly for testing. If you really want a constant source of zeros, try using the Constant Source block.
Parameters[edit]
None
Example Flowgraph[edit]
When a flowgraph has no hardware devices, a Throttle is needed to limit the CPU utilization. Since the "main" data flow is via messages, the Throttle is fed with a Null Source. This file can be found at [1]
