Electromagnetic coupling

Electromagnetic coupling

Introduction    A parallel application of electromagnetic (EM) modeling of aircraft is electromagnetic shielding and coupling. My recent post on calculating radar cross-section (RCS) looked at simplifying an airplane CAD model to a more simple canonical geometry, and...

Radar cross-section modeling

Introduction    Normal every day objects can be digitally represented through computer-aided design (CAD) models. Furthermore, these CAD models can be realistically sized, attributed, and imported into optical, mechanical, or radio-frequency (RF) models to help in...
The Fibonacci LFSR

The Fibonacci LFSR

Introduction    Welcome back! From our last conversation about general Linear Feedback Shift Registers, we mentioned there were two flavors of LFSR algorithms: Fibonacci and Galois. Although we ran through a basic implementation of the Fibonacci technique, we can dive...
Image-based audio processing

Image-based audio processing

Introduction    Audio and video are widely considered separate phenomena. After all, you listen to music, but you watch a show. On the other hand, both are the result of information streaming from one location to another, and being translated by a piece of technology....
Linear Feedback Shift Registers

Linear Feedback Shift Registers

 Introduction Linear Feedback Shift Register (LFSR) algorithms are an elegant solution in communication between satellites and their terrestrial receivers. Given the limited bandwidth of the receiver and transmitter systems, codes transmitted between the systems are...
