Question No. 1 [Marks: 7]
Determine Q output waveform for a negative edge triggered J-K flip-flop with preset, clear and J, K inputs. You are required to draw Q output waveform on timing diagram.
Question No. 2 [Marks: 1+2]
Provide to-the-point answers to the following questions:
- How does a synchronous counter differ from asynchronous counter?
- How many states does a mod-12 counter have? What is minimum number of flip-flops required?
Note: You can use Microsoft Paint or MS Visio to draw output waveform.
