1. A method comprising:
receiving, with a processor of a medical device, a first signal generated from a second signal; correlating, with the processor of the medical device, the first signal with a frequency component of a frequency band of the second signal, wherein correlating includes predominantly decreasing weighting of past portions of the first signal, and wherein predominantly decreasing weighting of past portions of the first signal comprises predominantly weighting present and more recent portions of the first signal more heavily than earlier portions of the first signal, and wherein the frequency band includes one or more frequency components; determining, with the processor of the medical device, a phase of the frequency component based on a filtered signal outputted from the correlation; determining, with the processor of the medical device, a phase of the frequency band based on the determined phase of the frequency component; and instructing, with the processor of the medical device, a therapy module to deliver therapy based on the determined phase of the frequency band. |
