Time controlling block

GNU Radio
1

Hi,
Today i got a idea about implementing three different modulations on
single message signal. But i want the modulations to happen after
certain
time has searched (can say exactly like counter). which is the block in
GNU
Radio that i can use has a counter.

Thanks and regards,
Sandhya

you could keep a class variable which is added to every time work() is
called, adding to it each time the value of noutput_items or
input_items.size().

Its also useful to know the scheduler, because it feeds work() an
arbitrary
number of samples each time.
There is a presentation on gnuradio scheduler.

This is redundant. The block base class has methods
nitems_read() and nitems_written() that do exactly what you want.

However: I’m totally interested in this presentation on the current
scheduler; URL?

Greetings,
Marcus

Marcus,

I think wayne is referring to the gnuradio scheduler presentation of Tom
Rondeau in his blog. The link is
