Calendar Description: Generation and nature of bioelectric potentials; electrodes and
other transducers; principles of instrumentation; electrical safety; neuromuscular and
cardiovascular instrumentation; ultrasonics and other medical imaging.
Course Objectives: Students will be able to apply the principles of electronic circuits
and devices to the use and design of instrumentation in the biomedical area. They will
have gained a basic knowledge of the operating principles of electrical and other
transducers, analog and digital instrumentation, applied signal acquisition and processing,
electrical safety in the medical environment, electrical properties of nerve and muscle
physiology; and instrumentation used in cardiopulmonary, neurological, surgical, and
rehabilitation areas of medicine.

Policy Reminders: “The Faculty of Engineering is concerned with ensuring an
environment that is free of all adverse discrimination. If there is a problem that cannot be
resolved by discussion among the persons concerned, individuals are reminded that they
should contact the Department Chair, the Sexual Harassment Officer or the Human
Rights Consultant, as soon as possible.”
“Students are reminded that they should read and comply with the Statement on
Academic Ethics and the Senate Resolutions on Academic Dishonesty as found in the
Senate Policy Statements distributed at registration and available in the Senate Office”
"Academic dishonesty consists of misrepresentation by deception or by
other fraudulent means and can result in serious consequences, e.g. the grade of
zero on an assignment, loss of credit with a notation on the transcript (notation
reads: "Grade of F assigned for academic dishonesty"), and/or suspension or
expulsion from the university. It is your responsibility to understand what
constitutes academic dishonesty. For information on the various kinds of
academic dishonesty please refer to the Academic Integrity Policy, specifically
Appendix 3, located at
http://www.mcmaster.ca/senate/academic/ac_integrity.htm
The following illustrates only three forms of academic dishonesty:

Plagiarism, e.g. the submission of work that is not one's own or
for which other credit has been obtained.
Improper collaboration in group work.
Copying or using unauthorized aids in tests and examinations.
