Python Visualisation._calc_inst_phase Examples

Example #1

 def test_calc_instant_phase2(self):
     t = np.linspace(0, 1, 50)
     S = t + np.cos(np.cos(4. * t**2))
     emd = EMD()
     imfs = emd.emd(S, t)
     vis = Visualisation()
     phase = vis._calc_inst_phase(imfs, 0.4)
     assert len(imfs) == len(phase)

Example #2

 def test_calc_instant_phase3(self):
     t = np.linspace(0, 1, 50)
     S = t + np.cos(np.cos(4. * t**2))
     emd = EMD()
     imfs = emd.emd(S, t)
     vis = Visualisation()
     with self.assertRaises(AssertionError):
         phase = vis._calc_inst_phase(imfs, 0.8)

Example #3

 def test_calc_instant_phase(self):
     sig = np.arange(10)
     vis = Visualisation()
     phase = vis._calc_inst_phase(sig, None)
     assert len(sig) == len(phase)
