Abstract
The embodiments described herein provide devices and methods to facilitate ripple control communication. Specifically, the embodiments provide devices and methods for decoding ripple control data from ripple signals, such as ripple signals that have been superimposed over power signals used to transmit power. These embodiments provide devices and methods that use band-pass filter, signal multiplier, fast and slow low-pass filters, and accumulate a difference between outputs of these slow and fast low-pass filters. This accumulated difference is then used to decode the ripple control data.
