- Draw any circuit (combinational, sequential to get this waveform)
- And gate with one input using buffer of another input for some delay
A is given waveform, we have to use circuits to get B and C waveform. For B we can use an And Gate with 2 inputs, X and Y. X is buffered (to get some delay) and is fed to Y input of And Gate. So we'll get waveform B.
But I don't know how to get C waveform. The question is that even if I extend A, then the falling edge of C must always occur one clock cycle before input A. Is this circuit even possible? I don't think so.
