| Details of Assignment | Example: Title:PSpice simulation design based on the diode circuits and transistor circuits. Objective:To introduce the use of software simulation tool (PSpice) to verify and analyze circuits. Type: Software Simulation / Program design and implementation Description: This assignment contains 2 questions on some diode and BJT circuits. Students will learn theoretically about circuit design, simulation and analysis. A tutorial on PSpice is provided for students to learn to use some of the functions of the software simulation tool. This assignment intends to provide opportunity for students to learn the basic skills in circuit design, simulation and analysis, thus the building up of the skills is highly dependent on students’ efforts. Guidelines are given along with the assignment questions. Students are advised to understand the way of design, the chosen conditions/considerations, the way of analysis, the information gained from the analysis, etc. |
