[Discuss-gnuradio] signal processing block output

[Ben Olsen]

Hi, 

Following up on my last question (thanks for replying Jonathan and
Eric!), I would now
like to have the data from gr_nlog10_ff() to manipulate, such as
printing on the
screen or eventually inputting into a simple threshold decision
block.  For the time being, I'd like to print to the screen. 
What would be the best way to do this, should I use a filesink or could
I take the data directly from the block?  Also, the
"noutput_items" that blocks return represents what exactly? I apologize
for my lack of software
saavy, I don't have that much experience!  

Thanks lots,
Ben
