摘要
本设计以凌阳16位单片机Spce061A和FPGA开发板为核心,由移相电路、放大整形电路、系统控制模块及显示模块等构成了多功能计数器。系统实现了移相、频率测量、周期测量、相位差测量等功能。系统移相可达0°到360°,频率测量可达20 MHz,精度可达到10-6。
The designer＇s core is Spce061A Electronics and the FPGA development board, by the phase-shifting circuit, to enlarge the plastic circuit, system control module and display module, and so constitute a multi-purpose counter. System achieve a phase-shifting network of measuring frequency, period measurement, single-chip phase measurement and control functions of several shows. The phase-shifting network achieve 0 degree to 360 degree the frequency can be measured 20M,accuracy up to 10^-6.
