Abstract:
Method for extracting component information waves from a combined information wave, said combined information wave comprising two or more component information waves of known and distinct frequencies and known wave forms and phases, said method comprising:a) a step of determining an amplitude of the combined information wave at the mid-cycle zero crossing point of each of the component information waves;b) a step of generating amplitude equations, one of the amplitude equations corresponding to each of the mid-cycle zero crossing points, with the sum of the unknown amplitude coefficients of each of the non-zero component information waves, as adjusted by the phase factor for the corresponding component information wave, being equal to the measured amplitude of the combined information wave at the mid-cycle zero crossing point; andc) a step of solving the amplitude equations to determine the amplitude coefficients of each of the component information waves.
