Re: [Discuss-gnuradio] Send zero-fill data when there's no input dato to process

[Marcus D. Leech]

Hello,

i have a message queue and some blocks that generate waveforms from the message input. The output of these blocks go to the USRP.

I need a block that when there’s no data to process (0 message in queue) generates zero-filled samples, to keep USRP busy.

I cannot find a similar block inside gnu radio sources. It’s possible?

Thanks

Just put a multiplier in there that under normal circumstances is '1', and when you want to zero-stuff, set the multiplier to '0'.
