[Discuss-gnuradio] Need examples of 'blocks'...

[John Clark]

I read the howto on 'blocks', however, since I'm sort of tuning into 
GNRadio applications, are
there examples of something like the following.

scenario 1:

Taking data from USRP, performing an FFT, then performing some 
'Algorithm', then
passing the results to the windowing processing to display results in 
graphical form.

scenario 2:

Take previously saved FFT data, passing through the Algorithms block, 
then to the graphics.

scenario 3:

Take either 'imput', and pass the stream through the Algorithms block, 
and save the raw
results to a file rather than the graphical output...

Had I tuned into this project earlier... this would have been the 
approach... however, I'm
inheriting a project... and would like to see if there are examples that 
would help me
put things together quickly...

Thanks
John Clark.
