Addendum to Course Description
The laboratory portion of this course provides students with the opportunity to develop skills in the operation of basic electronic test instruments (dc power supply, digital multimeter, signal generator, and oscilloscope). Students will work in teams of two or more to perform and complete laboratory exercises. Students must be able to communicate, both in oral and written form.
Intended Outcomes for the course
- Construct, analyze and troubleshoot circuits which incorporate sequential logic devices
- Operate electronic test equipment: multimeters, power supplies, signal generators and oscilloscopes.
- Read and interpret technical materials e.g. schematic diagrams and device data sheets.
- Communicate technical information in written and oral form
- Practice safe operating procedures.
The course will include a variety of learning activities. The lecture portion of the course will include instructor delivered lectures and demonstrations stressing key topics in the course. In preparation for the lecture portion of the course, students will be expected to complete all reading and homework assignments.
The laboratory portion of the course is intended to enhance skill in the operation of basic electronic test instruments, skills in circuit analysis and troubleshooting, skill in teamwork, and skills in oral and written communication. For each lab experiment the students will have to write a formal report.
Course Activities and Design
This course will include a variety of learning activities. The lecture portion of the course, two hours per week, will include instructor delivered lectures and demonstrations stressing key topics in the course.
