Generation of high synergistic signal in terrible environment and its FPGA implementation
Lu Da · 2006
The frequency difference of signals generated base on different crystal oscillator would change when signal generator is placed in a high temperature environment.This paper introduces a method of designing a signal generator which works in a high temperature environment.The approach based on FPGA technology and using Direct Digital Frequency Synthesis technology and Phase-locked loop technology.The paper also discusses the architecture of the signal generation system and the optimizing method.An experiment implemented strictly same as the working environment and result show good accordance with the design.
