Description: 设计一个4位的十进制数字式频率计测量范围为10MHz。量程分别为10kHz、100kHz、1MHz和10MHz四档。量程自动转换规则是：读数大于9999时，频率计处于超量程状态，此时显示器发出溢出指示（最高位显示F，其余各位不显示数字），下一次测量时，量程自动增大一档-Design a 4-bit decimal digital frequency meter measuring range is 10MHz. Range respectively, 10kHz, 100kHz, 1MHz and 10MHz fourth gear. Range automatic conversion rules are: reading is greater than 9999, the frequency meter range in a super-state, now display the instructions issued by overflow (up to digital display F, the remaining Members do not show figures), the next time measurement, the range automatically increases a file
