Excuse my ignorance but I need this spelled out for me. I am trying to come up with a phase demodulator to effectively perform the opposite function as the gr_phase_modulator_fc class. According to the code this is effectively doing output=complex(cos(in*sensitivity), sin(in*sensitivity)).
Is there a better approach than simply taking the real component of the output of gr_phase_modulator_fc and then doing: original_in = arccos(real(output)) / sensitivity Is there a block that already does this in grc? Thanks! -Phelps
