摘要
利用100KHz石英晶体、红外线光电门及十进制计数/七段译码器二合一集成电路,制做了测量精度可达0.01ms的红外数字毫秒计.
The article introduces one kind of digital millisecond counter which is designed by adopting 100KHz quartz crystal oscillator, infrared photoelectical switch and integrated circuit(composed of decimal counter/seven-phase decoder). The surveying precision of this kind of counter can be up to 0.01ms.
