Abstract
A method and apparatus for generating a poly phase signal set from a single signal output of a single phase instrument. The method comprising: generating a first signal output X representing the single signal output; processing the single signal output to generate a time delayed version Y_Raw of the single signal output by a time delay T; and processing the time delayed version Y_Raw to compensate for frequency changes in the single signal output and generating a second signal output Y of the poly phase signal set. The second signal output Y is displaced from the first signal output X by about 90 degrees.
