Disturbed digital signal filtering method, involves providing serial discrete input signal values of digital input signal, and determining filtered output signal value in dependence of last stored input signal value

摘要

The method involves providing serial discrete input signal values of a digital input signal, and storing the input signal values such that the last stored input signal value is provided for treatment. A filtered output signal value is determined in dependence of the last stored input signal value. An alteration time value for the output signal value is determined as a function of the determined output signal value. The input signal values are determined by a scanning device (120). A disturbed input signal is supplied to a level determination stage (110). An independent claim is also included for a digital filter for filtering a signal.
