If the input signal is to be rotated/shifted by 120 degree or 240 degree. I mean to refer the factors [a] and [a2] in sequence components.

With reference to the unsymmetrical fault analysis in power system, factors 'a'= -0.5+j0.866, 'a2'=-0.5-j0.866. Suppose I wish to generate the signal a2*Vb, where Vb is one of the phase voltage in...
