Question

Part 1 This section is just a quick check to make sure you understand how the equipment works. The circuit does not provide any useful function Nodes A and B represent inputs from the switch board while X represents an output displayed on an LED Check the chip information provided for chip pin-outs in particular the power supply connections. In general, you should place a couple of 100nF Multi-layer-ceramic (MLC) capacitors across the power supply lines to reduce electrical noise. This is not critical for such simple synchronous circuits involving FFs (e.g. counters). combinatorial circuits but becomes more important for Wire up the following circuit using 74HCoxx components provided. Spend some time choosing which gates in each package to use so as to keep your layout and wiring as simple as possible. diagram. Add pin numbers to the circuit Expected Truth table Schematic for Circuit Simplified Boolean Equation Use your constructed circuit to confirm the values in the truth tables Do these results agree with your expected values? YES/NO What simple logic functions do the two NAND-gates shown at ight provide? Draw two circuits that produce the same logic function as the above but based on a single NOR-gate. Draw a circuit that produces the same logic function as the above but based on a single XOR-gate Analysis and de mo OK (supervisor-mals) EEE20001 Digital Electronics Design

Answer 1

Given Diagram (ii) Do these results agree with you executed values - yes (iii) Not Gate (iv) X = A (+) B (v) Same logic function Produced x = A (+) B
