3.      To design analog electronic circuits, noting tradeoffs.

4.      To utilize computer programs to analyze and assist in designing electronic circuits.

5.      To hone problem-solving and written-communication skills in presenting a logical,  lucid flow in the solution of homework and test problems. 

6.     To accentuate the importance of listening, reading and recording as skills of life-long learning.

Course Objectives:
