title: Design of phase-detection algorithms insensitive to bias modulation.
abstract: For digital phase detection, the characteristic polynomial method permits algorithms that are insensitive to the harmonic content of the signal and insensitive to miscalibration to be designed easily. It is shown here that this method can also be used to design algorithms that are insensitive to a possible bias modulation of the intensity.
