IGIS Tech Notes describe workflows and techniques for using geospatial science and technologies in research and extension. They are works in progress, and we welcome feedback and comments below.

Discrete-time chaotic (DTC) map based true random number generators (TRNG) are cryptographic primitives, which its performance is scalable for the low power applications. In this paper, we analyzed ...

The Bilinear transform is widely used in IIR filter designing for the mapping of s and z planes. This transforms gives a stable first-order s-to-z mapping function. However, it suffers from frequency ...
