5.11.2 Input Line Debouncers
The Line Debouncer feature aids in discriminating between valid and invalid input signals and only
lets valid signals pass to the camera. The parameter value specifies the minimum time that an input
signal must remain high or remain low in order to be considered a valid input signal.
Note that the line debouncer delays a valid signal between its arrival at the camera and its transfer.
The duration of the delay will be determined by the debouncer value.
Figure 48 illustrates how the line debouncer filters out invalid input signals, i.e. signals that are
shorter than the parameter value. The diagram also illustrates how the line debouncer delays a valid
signal.
We recommend setting the parameter value so that it is slightly greater than the
longest expected duration of an invalid signal.
Setting the parameter value to a value that is too short will result in accepting
invalid signals. Setting the parameter value to a value that is too long will result in
rejecting valid signals.
