  • Apparatus for obtaining a pulse width of an unknown pulse signal
    Patent number: 6118390
    Abstract: An apparatus is provided for processing a pulse signal. The apparatus includes (1) a pulse-shrinking circuit for shrinking a specific quantity of a pulse width of the pulse signal; and (2) a feedback circuit electrically connected to the pulse-shrinking circuit for repetitively feeding the output pulse signal back to the input end of the pulse-shrinking circuit, the shrunk output pulse signal being further shrunk by the pulse-shrinking circuit in order to obtain a feedback number of the pulse signal before the pulse signal is vanished.
