Introduction to Circuits and Electronic enables students to attain knowledge of circuits and the integration of electronic components to obtain these circuits. It will impart skills to identify various electronic components, verify their operational characteristics and use them to design circuits which lead to a practical system. It introduces the fundamentals of the lumped circuit abstraction, the basic components of electronics such as resistive elements, diodes, transistors, amplifier and op amps. It examines the different ways to design basic analogue and digital electronic circuits for engineering applications.

Assessment Tasks and Weightings

To obtain a pass grade in this subject 50% overall must be achieved.

The subject assessment consists of a mini project (30%), five laboratory assignments (30%) and a final examination (40%) as summarized below. Students must also refer to the Subject Assessment Guide for Introduction to Circuits and Electronics. Detailed information is provided for each assignment.

  1. Mini Project The mini project provides students – working in groups – with the opportunity to undertake industrial project to apply their knowledge acquired in the lectures and tutorials to develop a solution to an industrial problem. This assessment contributes 30 % to the total marks for this subject.
  2. Laboratories There will be five laboratories to be conducted and assessed. Each laboratory will contribute 5% to the total assessment items mark of 30%. Before the start of each laboratory there will be a 5-minute quiz worth 1% of the 5% mark for each laboratory. The laboratory activities allow the student to prepare a professional level of application design. It involves undertaking an analysis of various circuits and design of minimum of 3 alternative circuits for specific applications.
  3. Final Examination: The final examination is of 2 hours duration consisting of two parts. The examination consists of Part A which is to evaluate their knowledge and Part B consists of a choice of two questions out of three questions. The final exam is worth 40% of the total marks for the Subject.

It is important that all students familiarize themselves with the PNG Unitech Assessment Guidelines including those on plagiarism. This can be viewed on the PNG Unitech website:
