Topics for term papers / Assignments / Students activities:
Assignment will be given when necessary and students are expected to make contribution during
lecture hours.
Alignment with Covenant University vision / Goals:
The advanced instrumentation concern with the description of instruments and their attributes so that
the magnitudes of and variation in, electrical, mechanical, and other quantities may be monitored in an
optimized manner for any measurement situation. The knowledge and experiences acquired in this
course is essential for the practicing engineer to have a thorough knowledge of electrical
instrumentation and measurement systems. This is especially so since in addition to his own
requirements, he may be called upon to advise others who have no electrical knowledge at all.
Therefore the area of application of this course meet the practical everyday need and will be valuable
to the new generation of Electrical Engineer to be raised.

Contemporary issues / Industry relevance:
Advanced Instrumentation is primarily intended to assist the student following an electrical or
electronic engineering degree course to adopt a practical approach to his measurement problems. It
will also be of use to industrial engineer or technician, who finds himself involved with measurements
in terms of volts, amperes, ohms, watts, etc, and faced with an ever increasing variety of instruments
from a simple pointer instrument to a complex computer-controlled system. The course is aimed at
practical conditions and situations rather than theoretical nicety hence help the engineer or instrument
user, to select the right form of instrument for an application, and then analyze the performance of the
competitive instruments from the various manufacturers in order to obtain the optimum instrument
performance for each measurement situation.
