Design and Implementation of Mixed Signal Measurement System Using FPGA

Abstract

This project presents the design and implementation of a measurement system using a Field-Programmable Gate Array (FPGA) and an Analog-to-Digital Converter (ADC) to process mixed-signal inputs and perform a variety of signal measurements. The system is capable of accurately measuring essential parameters of the input signal, such as voltage levels, 8 bit parallel digital data and 8 bit serial digital data (in formats like hexa decimal or Binary).The FPGA is responsible for the real-time processing of the signals and the extraction of these measurements, leveraging its parallel processing capabilities to ensure high-speed performance. The system integrates a USB-to-UART interface for communication between the FPGA and a personal computer. This interface enables the transmission of the measured data to the PC, where it can be displayed and analyzed via a user-friendly graphical interface. The measured values, including voltage, digital input are presented on the PC in an easily interpretable format, allowing for real-time monitoring and evaluation of the input signal.
