Digital Wideband Receivers

Learn the principles and state-of-the-art of digital microwave receivers with emphasis on wideband techniques and EW applications. Discover why the requirements for EW and communications receivers have become more closely aligned. Understand how placing the A/D converter closer to the antenna can preserve information. Understand the potential for future improvements and the device requirements necessary.

Instructor: James B.Y. Tsui, Ph.D.
