electronic counting apparatus

The electronic counter in this design has realized the measurement of frequency,cycle time and phase(difference) and implemented the intelligence coupled with the virtual instrument technology.

设计了电子计数器,实现了频率、周期和相位差的测量,并结合虚拟仪器技术实现了智能化。

From the principle of measuring cycle of electronic counter, it has been found out that the error of measuring cycles consists of three parts, that is, quantization error, timebase error and conversion error.

从电子计数器测量周期的原理出发,分析了测周误差产生的原因并指出测周误差由量化误差、时基误差、转换误差三部分组成,在此基础上提出了减小电子计数器测周误差的几种方法;为电子计数器在频率、时间间隔等参数测量时,如何减少测量误差提供了理论依据。

In our designed experiment for measurement of wave length by Michelson interferometer,the intensity change of interference fringe is transformed by optical electronic transducer into corresponding electrical signal changing,then it is amplified and renovated for use in electronic counter to measure more accurately the number of emerging or sinking interference fringes.

在迈克耳逊干涉仪测波长的实验中，用光电传感器元件将干涉条纹的强度变化转换为相应变化的电信号，经放大整形后由电子计数器测量干涉条纹涌出或陷入的个数，使波长测量更准确。
