Considering the following problem, What i know to convert from LP signal to BP signal is to:
- Draw the FD of the LP equation
- From it I can draw the FD for BP
- From this graph I can deduce the equation of the BP signal.
My problem here is that the equation has an Imaginary value, so how can i plot this equation and how can i deduce the graph of BP signal from it؟ because i searched and i found results about Hilbert transform and imaginary odd symmetry but i didn't figure that out.
