摘要
基于高精度恒误差测频原理 ,采用 Lattice的在系统可编程器件 ( isp LSI)进行数字频率计设计。结果表明 ,高精度恒误差测频原理是合理的。并对所采用的高精度恒误差测频原理作了深入的理论分析 ,给出了依据此原理实现的硬件电路。
This design is based on the theorem of fr e quency and period testing with high accuracy and constant error by using Lattice 's in-system programmablity device ispLSI in our hardware design. Every item of testing in our design demostrates that the theorem is reasonable. The further t heoretical analysis on the theorem is made in this paper.The hardware design is also given.
