Agreed.
[tim] One note on your nrzi_to_nrz code below. I don't know much about
compiler optimization but I suspect
nrz_bit = ! nrzi_bit ^ d_prev_nrzi_bit
might give you better performance than t
Thanks for the input Ed. Some comments below

Hello all,
I want to perform some simple boolean operations on a stream of data.
For example invert the bits from the output of the demodulators or convert
from NRZ to NRZI
I was thinking something like

or
2) maybe gr_boolean
Johnathan,
I have attached a patch to gnuradio-core/src/lib/gengen that provides
gr_xor_bb, gr_xor_ii and gr_xor_ss. The patch also contains qa code dumped
into gnuradio-core/src/python/gnuradio/gr
If this is the format you are looking for I will quickly gen up some other
boolean functions. If

This would be the way to go. Alternatively, you could create these
blocks as _ss or _ii, and work on packed data. Depending on where in
your flowgraph you need this operation, this would be mu
