Course Description: Lecture 3 hours. In this course concepts that will be studied include selected material from the Fourier transform, probability, random signals/noise, spectral analysis, information theory, sampling theory, encoding/decoding and digital signal modulation/demodulation. Matched filtering and quadrature detection for binary demodulation will be studied. Sampling theory will cover impulse and flat top sampling techniques. The modulation techniques covered will include On/Off Keying(OOK), Phase Shift Keying (PSK), Frequency Shift Keying (FSK), Direct Sequence Spread Spectrum (DSSS) and quadrature modulation and demodulation. Information theory will include topics of Channel Capacity, Entropy, and be applied to encoding/decoding techniques. Homework will be in the form of problem sets and MATLAB based visualizations or tutorials.

Prerequisites:ES 230, and ES 400; or consent of instructor.
