Development of portable testing device for high frequency carrier wave channels of electric wire
Tao He · Relay · 2006
The idea and way of intelligent testing instrument for electric wire high frequency carrier wave channels are introduced.Considering the feature of frequency band in high-speed sampling,the hardware for signal sampling and controlling is designed based on FPGA,which connects with PC through USB port.Digital signals extractive arithmetic and FIR filter are designed in digital signals processing.The device integrates the functions of display,processing and storage of computer.The intelligent testing instrument is a multi-functional system.This project is supported by National Natural Science Foundation of Hubei Province(No.2004ABA064).
