Question
Task 2 (LO2)
Explain and analyse the operation of a 4-bit asynchronous
binary counter, using D flip-flop that has a propagation delay
for 10 nanoseconds (ns). Develop a timing diagram showing the
Q output of each flip-flop, and determine the total propagation
delay time from the triggering edge of a clock pulse until a
corresponding change can occur in the state of Q3. Also
determine the maximum clock frequency at which the counter
can be operated. You should also:
Identify the pin out of a 4013 dual D-type flip-flop [or specify
an equivalent that you have available]
• Construct the schematic circuit of a 4-bit asynchronous
counter using D flip-flops in your ECAD package.
• Build a prototype circuit and verify that it works as expected,
and then compare the results from theory, simulation and
measurements.
• Now you need to Analyse, optimize and enhance the pervious
counter by converting it into an up/down counter, draw a
schematic diagram using ECAD package to show how logic
gates can be added making use of Timing Diagrams.
