I'm working on usrp1_source_s.cc to obtain an unpacked stream of 1 bit
samples into char variables (no changes for short). So, if I have 1, I
wish to use 0x00000001 and 0x00000000 for 0 value. I guess it is
reasonable, because after I can use unpacked_to_packed and
packed_to_unpacked to obtain a stream of bit of byte. I fault?

Because Peter Monta' patch use a mask like this 16'b0000000000000001, I
need to give to a 16 bit sample a 15 bit shift to take the SIGN. Isn't
it??
