1. A method for processing a signal, comprising:
- receiving the signal comprising a repetitive component;
identifying a plurality of features of the signal corresponding to the at least one repetitive component;
transposing a plurality of segments of the signal to form a stack of segments, the segments having as starting and ending points adjacent identified features; and
deriving information based at least in part from the stack of segments.

Abstract
The present disclosure relates to systems and methods for detecting features of a signal. According to embodiments, by transposing segments of a signal, such as segments representing pulses in a PPG signal, such that they are stacked next to each other, various characteristics about the signal may be discerned such as information about repetitive features of the signal. According to an embodiment, from a PPG signal respiration information may be determined about individual breaths, blood pressure changes may be determined, and information about other physiological parameters affecting the PPG signal may be determined.
