Delay line

GNU Radio
1

Dear Sir
I created a C++ sync block and inserted

out[i]=in[i-100]
I wanted to get 100th earliest sample continuously.
It worked. But I wanted to know will this correct when it connected to a
source continuously.
Thanks
Neil

You probably want to use the blocks.delay() block here.

Yes, it will.
The GNU Radio scheduler calls your block’s work() function whenever it
needs new data.

Anyway, this is a very basic principle of GR; I recommend working
through the “creating an OOT module” tutorial, it’s really great!

Greetings,
Marcus

Forgot to mention: You must call the set_history() function accordingly!
