gnuradio.gr: Modulation

gnuradio.gr.cpfsk_bc(float k, float ampl, int samples_per_sym) → gr_cpfsk_bc_sptr

Perform continuous phase 2-level frequency shift keying modulation on an input stream of unpacked bits.

Parameters:

• k – modulation index
• ampl – output amplitude
• samples_per_sym – number of output samples per input bit

gr_cpfsk_bc_sptr.set_amplitude(self, float amplitude)

gnuradio.gr.frequency_modulator_fc(double sensitivity) → gr_frequency_modulator_fc_sptr

Frequency modulator block

float input; complex baseband output.

gr_frequency_modulator_fc_sptr.sensitivity(self) → float

gr_frequency_modulator_fc_sptr.set_sensitivity(self, float sens)

gnuradio.gr.phase_modulator_fc(double sensitivity) → gr_phase_modulator_fc_sptr

Phase modulator block

output=complex(cos(in*sensitivity),sin(in*sensitivity))
