Courses

      • EE 3330-001 PROBABILITY AND RANDOM SIGNALS
        This is an undergraduate Probability course that covers the following topics:Probability, random variables, functions of random variables, random signals, noise. Statistical techniques and random variables for characterizing system response to noisy signals. Rigorous mathematical concepts will be tied to engineering system issues such as characterizing uncertainty due to measurement error, component and system tolerances, and noise sources such as device noise, quantization noise, communication channel noise, and thermal noise. Prerequisite: Grade of C or better in EE 3417. Co-requisite: EE 3318.
