AI summary

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.
