If you took the input and ORed it with output from a two-stage shift register, you would get the output shown here. But like everyone else has said, you need to be able to ask enough of the right questions to find out what the real design intent is.Strictly spoken, a waveform can't work as complete design spcification, because it tells only about specfic cases. In the present case, we can only guess, that the circuit performs a pulse extensions of 2 clock cycles under all condtions. There must be a describing text.
Secondly, the waveform must be unequivocal. The shown one is just the opposite, showing a timing that can't be implemented in a real circuit, because input edge, clock edge and output edge seem coincident. It seems to have been sketched carelessly, without considering real logic behaviour.
