| Rationale:      | Engineering technologists, such as those holding engineering diplomas, often work  with  a  variety  of  electronically  operated  and  controlled  equipment.  To  use  and  maintain  such  equipment  effectively,  they  need  to  apply  fundamental  principles  of  electronics  and  electrical  engineering  to  solve  the  various  problems  they  will  encounter throughout their careers.  A  solid  understanding  of  the  functions  of  basic  electronic  devices  and  circuits,  coupled  with  practical  skills  acquired  in  the  laboratory,  is  essential  for  these  technologists.  This  knowledge  will  aid  them  when  working  with  electronically  controlled  or  operated  equipment  and  electronic  circuits.  Therefore,  this  course  is  designed to ensure that students can effectively use and apply the principles of basic  electronics whenever required. |

## GUJARAT TECHNOLOGICAL UNIVERSITY

Program Name: Diploma in Engineering Level: Diploma Branch: Computer Engineering/ Computer Science and Engineering / Cyber System and Information Security Course / Subject Code : DI01000151 Course / Subject Name  :  Basics of Electronics

## Suggested Project List:

Each student will work on one micro-project assigned at the beginning of the semester. In the first four semesters, these projects will be group-based, with 3 to 5 students per group. In the fifth and sixth semesters, groups will be limited to a maximum of three students.

The  micro-projects  can  be  based  on  industry  applications,  internet  research,  workshops, laboratory  work,  or  field  studies.  Each  project  should  cover  two  or  more  Course  Outcomes (COs)  and  integrating  Practical  Outcomes  (PrOs).Students  must  keep  a  dated  work  diary documenting  their  individual  contributions  and  present  a  seminar  on  their  project  before submission. The workload for each student should be around 16 hours (approximately one hour per  week) throughout the course. Projects should be submitted by the end of the semester to help students develop industry-relevant skills.

Here  is  a  suggestive  list  of  micro-projects,  which  should  align  closely  with  the  course's competencies and COs. Similar projects may be added by the course teacher:

Using  fundamental  knowledge  of  electronics,  students  can  develop  mini  or  microprojects  based  on  team  or  individual  work.  These  projects  should  strengthen  their understanding of electronics hardware and serve as prototype models for various societal applications.

## Suggested Activities for Students:

In  addition  to  classroom  and  laboratory  learning,  the  following  student-related  co-curricular activities are suggested to help achieve the various course outcomes:

1. Group  Activities  and  Reports :  Students  should  conduct  the  following  activities  in groups and prepare small reports (1 to 5 pages each). For micro-project reports, follow the suggested format. For other activities, students and teachers can decide on the format together. Students should also collect and record physical evidence, such as photographs or videos, for their portfolios, which will be useful during placement interviews:
- a. Prepare charts or display boards of some electronic devices with their specifications.
- b. Undertake mini or micro-projects in teams or individually.
- c. Give a seminar on any relevant topic.
- d. Conduct a market survey of various types of hardware components.
- e. Prepare showcase portfolios.
