TASK 1: LO3.1 a) Using Manufacturer's datasheets complete a table using Nominal values for the following logic families: LS TTL, ALS TTL, CMOS, HCMOS. (Include excerpts from datasheet in appendix) b) Briefly explain the different types of scales of integration: SSI, MSI, LSI, VLSI. (one sentence each) c) Briefly explain the different types of programmable devices: PROM, PAL, PLA. (one-two sentances) TASK 2: (LO3.2 & LO3.3) You are to design a 3-bit counter with outputs Q0, Q1, Q2, where Q0 is the least significant bit. The sequence 0, 2, 3, 5, 7, 6, 4, 0, 2 … is generated: 010 (2) 011 (3) 101 (5) 111 (7) 110 (6) 100 (4) 000 (0) Then repeat   Part 1 Design the circuit in multisim. (Use any type of flip-flops eg JK T or D, and any gates) Include truth tables and Karnaugh maps in your answer Opportunity for merit Design the circuit in multisim using only another type of flip-flop and NAND gates logic. M2 Opportunity for merit Re-design the circuit in multisim with an UP/DOWN counter input, so that the sequence can be reversed. The counter has a single input D, when D is low the counter counts up the sequence, when D is high the counter counts down the sequence. Use the Moore model (This requires outputs to be decoded) Your answer should include truth tables, Karnaugh maps. M1 Part 2 Using circuit simulation software, draw a circuit diagram from Task 2, Part 1 and simulate its operation. Demonstrate the circuit operation to your tutor. Opportunity for Distinction Re-design the circuit in multisim with an UP/DOWN counter input, so that the sequence can be reversed. The counter has a single input D, when D is low the counter counts up the sequence, when D is high the counter counts down the sequence. Use the Mealy model. Your answer should include truth tables, Karnaugh maps and be made using only JK type flips flops. Demonstrate to your tutor that the circuit works using simulation software.D3   TASK 3: (LO3.2B & LO3.3B) Part 1 Design a circuit using only NAND gates, whose output goes HIGH when its inputs are: A is high and B is low and either input C or input D is also HIGH and make a sketch. Derive a Boolean equation that describes the performance of the required circuit. Part 2 (LO3.3B) a) Using a 'a multsim design and construct the circuit using the output connected to a LED or Logic-probe, and produce a four-variable truth table and apply all combinations of input variables to the circuit and each time note the logical state of the output. b) Demonstrate and test the circuit operation for your tutor. Opportunity for distinction You need to demonstrate that you have completed the assignment without support from your lecturer or peers. D2
