Figure 2
Synthesised LFI signal with \({\varvec{C}} =\) 0.5, \({\varvec{\alpha}} =\) 0.5, amplitude \({\varvec{\beta}} =\)1 and phase \(\phi =\)0 (black dashed line) along with the SM voltages \({\varvec{V}}_{{{\mathbf{SM}},{\varvec{i}}}}\) sampled in three exemplar sets of \({\varvec{N}} = 4\) equally spaced phase points \(\phi_{{{\varvec{L}},{\varvec{s}}}} = \phi_{{\varvec{i}}}\) (with \({\varvec{i}} = 0 \to 3)\) with \(\phi_{{{\varvec{i}} = 0}} = 2\user2{\pi m} + 0\) (blue circles), \(2\user2{\pi m} + {\varvec{\pi}}/6\) (red circles) and \(2\user2{\pi m} + {\varvec{\pi}}/3\) (green circles). Also shown (coloured solid lines) are the corresponding functions \({\varvec{V}}_{{{\mathbf{SM}},{\mathbf{m}}}} = {\varvec{\beta}}_{{\varvec{m}}} \cos \left( {\phi_{{{\varvec{L}},{\varvec{s}}}} - \phi_{{\varvec{m}}} } \right)\) plotted using the values of \({\varvec{\beta}}_{{\varvec{m}}}\) and \(\phi_{{\varvec{m}}}\) determined from the GDRA applied to each set of \(\phi_{{\varvec{i}}}\).
