College of Technology

University of Houston

 

Control Instrumentation , ELET 3304, covers measurement sensors along with the analog and digital signal conditioning required to provide information to measurement systems and control systems.  This course has a prerequisite of solid-state electronics and differential calculus.  Integral calculus is recommended as a co-requisite along with the laboratory, ELET 3104.  The objective of the course is to learn how to design and implement measurement systems through the selection of an appropriate sensor and development of appropriate signal conditioning.

GRADING POLICY:

 

1.     There will be two 1.5 hour in-class exams.  The final will be counted twice.  The homework will be averaged to constitute a single exam grade.

2.     The lowest exam score will be dropped (not the homework,  if the lowest is the final it will be dropped once)

3.     The highest three exam scores and homework score will be averaged to obtain the course score.

4.     The course grade will be based upon the course score.
