Abstract
In modern days, the need for fast and efficient control of information is extremely important for all scientific applications. It is proven that in the digital age that we live in, most applications are more efficient than they used to be and data volume much more manageable. Therefore, the development of digital systems that can modulate and demodulate this data volume is imperative.
Digital systems, as a continuation of the technological innovations of the past, such as the first quantizers and modulators, have advantages over their analog counterparts. The developments of very large scale integration circuits and field program gate arrays have improved drastically many features of modern digital systems and reduced hindrances such as timing issues and noise.
The purpose of our work is to develop a digital I/Q demodulation circuit. This system is developed both in High level using Matlab, for conducting simulations, and Low level using the VLSI design platform, Xilinx Vivado. The results of those designs were analyzed and compared to each other to ensure their functionality. Finally, there was a discussion about possible applications and extensions of the designed I/Q demodulator system that was created.
