Debouncing input signals
For input signals with a bouncing characteristic, a debounce function can be
configured. This means that the first change of the input signal causes the
debounced input signal to be changed and then be kept on this signal value
for the duration of the debounce time.
The debounce function is placed after the deglitch function described above
and both are realized by the firmware of the CMC 353 and are calculated in
real time.
The figure below illustrates the deglitch function. On the right-hand side of
the figure, the debounce time is too short. As a result, the debounced signal
rises to “high” once again, even while the input signal is still bouncing and
does not drop to low level until the expiry of another period T
