Goals/Objectives: To provide the student with certain advanced circuit theory concepts that relate to the understanding of how single pulses and pulse trains are processed by circuits containing R, L, and C components. Also, the student should be able to correlate the time domain and frequency domain representations of complex signals. The student should be able to also design logic circuits using Programmable Logic Devices (PLD’s) and the 555 timer. The companion laboratory course, EET 427L, closely tracks this lecture course.
