RE: [Discuss-gnuradio] How to change the phase of a signal

[Moir, Tom]

You can change the phase of a signal at a given frequency quite easily but if 
you need to phase shift an entire spectrum you will need a Hilbert Transform.

hi ,

i am not very sure if this is what u are asking for but u can change
the phase of a signal by altering the imag and real part of the
signal's value .. u can do this by multiplying it with a complex
constant if you want a constant phase shift
