　　 中文摘要:
　　 本次设计一个利用74LS160计数的简易数字控制电路，由NE555产生频率为1HZ的输入信号，经过74LS48译码由数码管显示。当数字大于100时有指示灯显示，大于300时返回。

　　 英文摘要:
　　 The design a makes use of a machine of 74ls160 count of a simple number control circuit, it produced import-signal frequency was 1Hz. Through 74LS48 decoded using numeral display. The valve lighting when the number more then 100. If the number more then 300 it will go to once again.
　　 The design is a simple digital control circuit . It makes use of a integrated circuit unit 74ls160 counter . The input signal’s frequency of the circuit is 1HZ pulse which generated by NE555.the common negative pole is drived by seven sections decoder .The LED will bright when counting number is above 100 and it will be off when above 300 .At the same time, the negative pole will show ZERO ,the counter will restart . All of the procedures in the working satus are sure of no showing ZORES which are not significant.
　　 Key words:
　　 Oscillation Count Decode
