SYDE 292 Circuits, Instrumentation and Measurement
Course Objectives, Operation Format, Outline, and Schedule
Objectives:
In general, the course hopes to provide an overall understanding of the elements and processes, including
sources of errors, involved in obtaining electrical analog measurements and digitally acquiring these
measurements.
The course specific objectives are to develop an understanding of:
voltage, current, resistance, capacitance, and inductance;
voltage and current supplies, resistors, capacitors, inductors and diodes;
techniques for analyzing simple circuits when driven by
initial conditions or direct or alternating power sources;
important basic circuit concepts such as transfer function, loading effects and frequency response;
operational amplifiers and circuits using operational amplifiers;
filters, transducers and D/A and A/D converters;
the concept of a measurement channel and
possible sources of error when performing electronic measurements.
Lectures, regular laboratory work and periodic assignments are used to pursue the course objectives.
Operations Format:
This laboratory course consists of nine labs. Each lab will require preparation time (as indicated in each lab),
about three hours in the laboratory (CPH 1335A) and a few hours of write-up time. Three to four hours of
lectures each week will be used to present pertinent theoretical and practical concepts involved with the
laboratory exercises. There will be periodic assignments that will help you gain design experience and a “hands
on” mid-term examination that will test your practical knowledge. A final exam will test your analytical skills.
1. Laboratory Groups: There are to be about 35 groups each consisting of three students. It is your
responsibility to form groups consisting of three students and to register your group on the sign-up sheet
outside the lab. The groups are classified according to day (Mon., Tues., etc.) and section (1-7), so simply
choose a day most accommodating to your course schedule and register in room CPH 1335.
2. Submission of Reports: All reports must be submitted in a professional form, with any diagrams and
tables clearly labeled. Note the following points;
i) Only one report per group,
ii) Reports are to be submitted to the collection box outside of E2-1303B within 1 week of the end of
your scheduled laboratory time. Late reports with no responsible excuse will be given half marks.
3. Format of Report:
i) Front page with - title of lab - group number - student names and I.D. numbers laboratory period
ii) Introduction - concepts covered
iii) Preparation and design as required
iv) Results - tables, graphs, etc.
v) Summary of results
vi) Conclusions
date of
4. Notes: A Laboratory manual, suggested readings and copies of the overhead diagrams used in class will be
available at the UW Book Store. It is strongly suggested, that for each group, a lab book be acquired and
maintained to record pertinent circuit diagrams, instrument and power supply settings and results. Lab
books can be very helpful during the completion of lab reports.
5. Conduct: The laboratory will be open from 2:30 to 5:30 Monday to Friday. Attendance at each lab will be
recorded and unprofessional conduct will be noted. There is to be no food, drink or smoking in the
laboratory.
6. Grading: Assignments will be not graded. Solutions will be posted within a reasonable time after the handout date. The approximate mark distribution for this course is given below. The instructor reserves the right
to alter these weights slightly and it is usual that a "pass" in this course requires a "pass" of both the mid-term
and the final exam.
