1. A system for characterizing periodic component of a first signal, the system comprising a processor configured to:

  • obtain second signals representative of intensities of captured electromagnetic radiation, each corresponding to a respective different radiation frequency range;

    analyze the second signals by applying a transformation to the second signals to form transformed signals such that any value of the transformed signals is based on values from each of the second signals at corresponding points in time;

    combine the transformed signals into an output signal; and

    obtain values of variables determining influences of components of the second signals on the output signal by at least one of;

    select at least one value of at least one parameter corresponding to a respective one of the variables; and

    calculate values of at least one time-varying factor corresponding to a respective one of the variables, and perform a normalization of the second signals using the calculated values.
