Currently Teaching
CPET-343
Hardware Description Language
3 Credits
This course is a more in depth coverage of current logic design and verification methodologies using a modern hardware description language (HDL). Topics include coding for different levels of abstraction; implementation of arithmetic circuits and finite state machines, hierarchical designs, reusable component design, data and control path, best coding practices, design constraints and verification. The laboratories are designed to illustrate concepts, reinforce analysis and design skills, and develop instrumentation techniques associated with the lecture topics.
EEET-261
Fundamentals of Audio Engineering
3 Credits
This course provides a fundamental study of the technology and practice used in recording, editing, mixing, production, and distribution of sound. Topics include microphone types, selection and application the mixing console, mixing techniques and introduction to Signal Processing equipment and associated techniques, an introduction to the concepts relating to digital audio technology such as sampling, the Nyquist theorem, alias frequencies, quantization, dynamic range, compression and their applications will be covered.

EEET-461
Introduction to Acoustics
3 Credits
This course introduces the student to sound as both a physical and psychological phenomenon. The course explains the nature of sound in terms of acoustic pressure and provides an overview of how humans receive and perceive sound. Sound waves are also introduced, starting with the development of the acoustic wave equation and its solution for plane and spherical waves with harmonic sources. The concepts of acoustic intensity and acoustic impedance are presented. The course also includes study of basic sound sources as well as the absorption, reflection, scattering and diffraction of sound by various physical structures.
