Assignment Brief and Guidance: 

You have just been employed as an Electronics engineer at Gizmos Electricals, a high quality 

electronic retail and repair shop, which deals with various analogue and digital electrical products. 

You will be working on a variety of electronic products, including the study of fundamental electrical 

quantities to analyse simple circuits, analogue and digital electronics and amplifier characteristics. You 

will be testing various electronic products coming in to the shop and apply your knowledge of 

electronics to analyse them. As a part of your job, you will also have to give training to the interns on 

different topics like the difference between analogue and digital electronics, their relative applications 

and benefits, by giving examples wherever applicable. 

Case 1 – Laboratory Portfolio 

Perform the following test experiments in the lab by applying your knowledge of Electronics. Produce 

written reports to include results, analysis, evaluation and conclusion. 

1) Test a digital Multimeter to check the battery voltages and resistors. 

2) Experiment demonstrating Ohm’s Law 

3) Experiment demonstrating Kirchhoff’s laws 

(Parts 1 to 3 cover P1, M1, D1). 

4) Experiment demonstrating periodic waveforms 

5) Experiment exploring R-L, R-C and R-L-C circuits 

(Parts 4 and 5 cover P2, M2, D2) 

6) Experiment demonstrating rectification and smoothing. (P4, M3, D3) 

7) Conduct a lab experiment demonstrating simple logical functions with electronic logic gates (P7) 

Case 2 – Report 

You need to prepare a report for interns, with sections, to explain the following 

1) Explain the characteristics of a typical amplifier, giving examples of where this type of circuit is 

used. (P6) 

2) Explain the difference between digital and analogue electronics, giving examples of each. (P5) 

3) Describe the applications of analogue and digital electronics, (using the examples from parts 1 

and 2), and critically evaluate the advantages and disadvantages of each. (M4, D4)
