Techniques for filtering multi-component signals
First Claim
1. A system for separating components of a multi-component signal, the system comprising:
- signal splitting means for replicating a multi-component signal on a first signal processing path and a second signal processing path;
signal filtering means for removing a modulated data component from the multi-component signal on the second signal processing path;
signal separation means for coupling signals received over the first signal processing path and the second signal processing path to destructively generate a difference signal when the signals are received in-phase,wherein the difference signal comprises the modulated data component of the multi-component signal; and
signal delay means for delaying signals on the first signal processing path or the second signal processing path so the signals are received in-phase at the signal separation means.

Abstract
Techniques are described herein for filtering and/or otherwise isolating or extracting components of multi-component signals. More specifically, embodiments of the present disclosure describe techniques for filtering and/or otherwise extracting a continuous wave component (or wireless power component) and a modulated data component from a multi-component signal. In some embodiments, the techniques describe systems, apparatuses and methods for filtering and/or otherwise isolating or extracting a frequency (e.g., modulated data component) from a continuous wave (e.g., wireless power component) without affecting the levels of other frequencies. The individual components or signals can be transmitted by one or more sources and received at one or more existing antennas of an electronic device simultaneously.
