Abstract
Methods, systems, and apparatus for detecting a center frequency of an input signal, the input signal including a carrier signal modulated with a modulation signal. Detecting a frequency of a second signal. Determining a difference signal between the center frequency of the input signal and the frequency of the second signal. Modifying the frequency of the second signal based on the difference signal to provide the carrier signal. And, outputting the carrier signal.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A method of extracting a carrier signal from a modulated signal, the method comprising:
detecting a center frequency of an input signal, the input signal comprising a carrier signal modulated with a modulation signal; detecting a frequency of a second signal; determining a difference signal between the center frequency of the input signal and the frequency of the second signal; modifying the frequency of the second signal based on the difference signal to provide the carrier signal; and outputting the carrier signal.Cited by (0)
