Digital signal x must retain the value "1" without interruption during time
T, before output y switches to "1".
Digital signal x must retain the value "0" without interruption during time
T, before output y switches to "0".
First-order delay element.
pxxxx = Time constant
Digital signal x must retain the value "1" without interruption during
time T1 or the value "0" during time T2, before output y switches its
signal state.

The rising edge of a pulse at input X sets output Y to
1 for pulse duration T. The pulse generator
cannot be retriggered. At T=0, a pulse duration of one cycle applies.
