ET 3060 - Signals, Circuits, and Systems II

4 lecture hours 0 lab hours 4 credits
Course Description
Electronic signals and noise, especially in the frequency domain, and the corresponding system responses are examined in this course. Topics include the Fourier transform, the exponential Fourier series, and spectral densities of signals including noise. A significant portion of this course examines digital signals, sampling, A/D and D/A converters, and an introduction to digital signal processing using the Z-transform. Practical applications are discussed throughout the course. (prereq: ET 3001 )
