Course Objectives

Students develop a solid understanding for analysis of communication signals in time domain and frequency domain. Students learn to design and simulate many types of communication circuits, and then assemble, measure, and evaluate the circuits using laboratory instruments. Students develop competency in measurement science by utilizing modern advanced instruments, which are similar to instruments presently being used by engineers in industry.
