Abstract:
A phase detection system includes first and second phase mixing circuits in signal communication with a signal phase adjuster module. The first mixing circuit generates a first digital modulated frequency signal based on an input signal and a first reference phase signal. The second mixing circuit generates a second digital modulated frequency signal based on the input signal and a second reference phase signal, which phase shifted with respect to the first reference phase signal. The phase detection system further includes a phase identification (ID) module in signal communication with the first mixing circuit and the second mixing circuit. The phase ID module generates a phase signal based on the first digital modulated frequency signal and the second digital modulated frequency signal. The phase signal indicates a phase of the input signal.

Claim (Index 12):
A method of measuring a phase-modulated signal with changing amplitude, the method comprising:\n generating, via a signal phase adjuster module configured, a first reference phase signal having a first phase a second reference phase signal having a second phase that is offset with respect to the first phase; generating, via a phase identification (ID) module, a first modulated analog signal based on an input signal and a first reference signal; generating, via the phase identification (ID) module, a second modulated analog signal based on a second reference signal and the input signal; generating, via a phase identification (ID) module, an output phase signal based on a phase differential (\u03c6) between a first phase angle of the first modulated analog signal and a second phase angle of the second modulated analog signal; receiving, via a low pass filter in signal communication with the phase ID module, a phase-offset reference signal having a phase that is offset with respect to the initial phase of the reference signal delivered to the first stage; and outputting a filtered low frequency signal based on the output phase signal and the phase-offset reference signal, wherein the low frequency phase signal includes the phase indicated by the phase signal, and wherein the input signal is mixed with the phase-modulated reference signal to generate a modulated frequency signal including high frequency components.
