[Discuss-gnuradio] gnuradio block for boolean operations

[Tim Meehan]

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 
 1) gr_xor_bb, gr_and_bb, gr_or_bb, br_not_bb ...
or 
 2) maybe gr_boolean("xor") , gr_boolean("and") ...

Is this something someone has started?

Is there another way I should go about this?

If this is something that should be done can someone give me an idea of the desired format (1 or 2 or something else)

Tim
