Re: [Discuss-gnuradio] Getting time each time power squelch is on

[Luis Colunga]

Hello sreeraj,

I am checking those examples, thanks. Can you elaborate with what you
mean with math manipulations?? Even if I am using tagged_file_sink can
I interpret what is generated as if they were audio wav files?

Thank you.
