The designed decoder on Multisim

Briefly summarise your project and steps followed to accomplish it. This should be written last and should be short (about 100 to 150 words). It should emphasize briefly the basis or reasons for the experiment. In addition, the methodology/ procedure, analysis, significant findings, conclusions and recommendations are also expected to be summarised concisely (in few sentences bearing in mind the number of words limitation).

The introduction should include an introductory paragraph that details the relevance of this lab to the demonstration of engineering principles.

A few paragraphs should be written that give good examples of where this work occurs in industry/ engineering design etc (Provide some figures of relevant application).

Introduce very briefly the rest of the Lab report sections here.

Hardware design (15 Marks)

Provide a brief description of all elements used in building the circuits (Push buttons, Pull-up resistors, Inverters, decoders, 7-segment resistors and 7-segment), suggestions and further improvements. Use the datasheets provided via Moodle or any other references. Use Harvard referencing guide found on Moodle.

Figure 4: Priority encoder

Figure 5: Common Anode 7 segment display (Source: ElectronicsTutorials)

Use Harvard referencing.

Design and simulation (35 Marks)

Figure 1: The simulated circuit on Multisim

Re-design the SN7447A IC using logic gates, explain how and what you have done. Provide background theory and math (Boolean) where appropriate.

Table 1: Truth table

Clearly labelled photographs or schematics (often preferable) of the equipment are required.

Figure 2: The designed decoder on Multisim

It is important to show evidence of deep gained knowledge.

Conclusions and Recommendations (5 Marks)

This section (100 – 200 words) should briefly summarise the main conclusions of the laboratory exercise. What comes first, simulation or hardware construction? How simulation helped in building and understanding the experiment? How can the results be used in a real engineering context? Was the circuit stable? How can the experiment be improved? What further research would you undertake to further investigate the question if you had the time and resources?
