A Novel High Precision Frequency Comparison System
Yao Xi-qin · Yuhang jice jishu · 2010
A new high precision frequency comparison system based on the idea of the Lisaajous curve processing and the concept of the equivalent phase comparison frequency is introduced in this paper.Lissajous curve with short image cycle periods can be caught and signals with large frequency difference can be compared by this system.The system can be built up by some simple devices,but the measurement precision can be improved significantly.
