static sptr gr::blocks::probe_rate::make ( size_t  itemsize,
double  update_rate_ms = 500.0,
double  alpha = 0.0001 
) [static]

Make a throughput measurement block.

Parameters:
itemsizesize of each stream item
update_rate_msminimum update time in milliseconds
alphagain for running average filter
virtual double gr::blocks::probe_rate::rate ( ) [pure virtual]
virtual void gr::blocks::probe_rate::set_alpha ( double  alpha) [pure virtual]
virtual bool gr::blocks::probe_rate::start ( ) [pure virtual]

Called to enable drivers, etc for i/o devices.

This allows a block to enable an associated driver to begin transfering data just before we start to execute the scheduler. The end result is that this reduces latency in the pipeline when dealing with audio devices, usrps, etc.

Reimplemented from gr::block.

virtual bool gr::blocks::probe_rate::stop ( ) [pure virtual]

Called to disable drivers, etc for i/o devices.

Reimplemented from gr::block.
