3-bit shift register • Identify the pin out of a 74HC74 dual D-type flip-flop with positive edge trigger [or specify an equivalent that you have available]
• Construct the schematic circuit of a 3-bit shift register using D-type flip-flops in your ECAD package. The 74HC74 in the schematic has Set and Reset pins held high (logic 1) to allow changes at the D pin to clock through to the output Q. [or give equivalent detail for D-type available.]
(i) Use the schematic to simulate the behavior of the circuit by setting data values at the D1 input and clocking them through (show your result; insert a screenshot of your work for all cases.).
(ii) Build a prototype of the circuit and demonstrate that it works as expected, and then compare the results from theory, simulation and measurements
(iii) What practical improvements would you make to the circuit (Simulate your idea and insert screenshot of your work)?
(iv) The circuit above shifts data from left to right. Draw a schematic diagram to show how logic gates can be used to enable the data to be shifted from right to left.
(v) Simulate the circuit designed in (iv) to demonstrate how the circuit can shift data from left to right or right to left (show your result; insert a screenshot of your work for all cases.).
