The Reason this Course is in the Program:
This course represents the very basis of the whole electronics. Although covering essentially the analog principle, it also is the point of departure for digital electronics. The digital aspect is being pursued and deepened in CEEN 3100. The analog aspect is impacting the high-frequency classes in Computer Engineering.
