What is the minimum signal time?
In contrast to the debounce time, a telegram is only sent after
the minimum signal duration has elapsed.
The individual functions:
If an edge is detected on the input, the minimum signal duration
will commence. No telegram is sent on the bus at this time.
The signal on the input is observed within the minimum signal
duration. If a further edge appears at the input during the
minimum signal duration, it will be interpreted as a new
operation and the minimum signal duration restarts.
If the input signal duration has not changed during the minimum
signal duration, an edge is detected and a telegram is sent on
the bus.
Example: Minimum signal time of the input signal
for a detected edge:
Input signal
Detected pulse edge
As only two edges remain stable for the minimum signal time
T
, only these are detected as valid.
