1. A method for smoothing a time-varying level of a signal, the method comprising:

  • estimating a time-varying probability density of the time-varying level of the signal;

    computing a probability of a prior smoothed time-varying level using the time-varying probability density estimate;

    adapting a smoothing filter in response to the probability; and

    applying the adapted smoothing filter to the time-varying level to generate the smoothed time-varying level.
