Homeworks, Quizzes, Projects:

Each student individually prepares a term project related to the course subjects.

Computer Usage:

Computers  will be one of the main tool using a programming languages such as Object Bench or LabVıew , Matlab, Visual Basic, C, Fortran, etc.

Laboratory Work:

Most of the work will be done in the Electronic Lab and all of the electronic components will be supplied by students who take this course. The list of the components will be given in the first lecture.
