by introducing an initial value at the beginning of the output signal.
Note, that this implies that there is one event (the first) at the
output signal that has no corresponding event at the input signal.
One could argue that input and output signals are not fully synchronized,
even though all input events are synchronous with a corresponding output
event. However, this is necessary to initialize feed-back loops.
