[Commit-gnuradio] Help with <cos^n>

[address@hidden]

Hi all,

I've started to use GNURadio just a month ago.

I've read the tutorial, and I've done some examples with GRC.

I'm trying to build a flowgraph that implement a math formula and I'm not sure how calculate the "cosine^n" on Gnuradio.

Anyone can hel me, please?

Otherwise, I've tried to create a hier block but when I select Create Hier nothing happens, but every blocks become grey and gnuradio stops to work. Do you know why? Is anything I should know before creating a hier block?

Thank you for your timea and your willingness.

Connie
