1. A method of performing a time-to-digital conversion between edges of a first signal and a second signal, wherein said first signal transitions between states rapidly with respect to said second signal, comprising the steps of:

  • passing said first signal to a string of logic devices during a time period sufficient to allow the first circuit to reach a desired state prior to an active edge of the second signal and not passing the first signal to the string of logic devices during other time periods;

    storing a state associated with said string of logic devices responsive to the active edge of the second signal.
