Nexperia系统声音实现的源码，解压密码没有

采用一个标准的基准时钟，在单位时间如1S里对被测信号的脉冲数进行计数，即为信号的频率，由于闸门的起始和结束时刻对于信号来说是随机的，将会有脉冲周期的量化误差，进一步分析测量准确度。因此直接测频法只适合测量频率较高的信号，不能满足在整个测量频段内的测量精度保持不变的要求。若要得到整个频段内较高的精确度，应该考虑等精度测量等其他方法。

8051工作于11.0592MHZ,RAM扩展为128KB的628128,FlashRom扩展为128KB的AT29C010A 128KB的RAM分成4个区(Bank) 地址分配为0x0000-0x7FFF 128KB的FlashRom分成8个区(Bank) 地址分配为0x8000-0xBFFF 为了使8051能访问整个128KB的RAM空间和128KB的FlashRom空间,在CPLD内建两个寄存器 RamBankReg和FlashRomBankReg用于存放高位地址-8051 works in 11.0592MHZ, RAM expansion for the 128KB of 628128, FlashRom extended AT29C010A 128KB to 128KB of the RAM is divided into four zones (Bank) Address Assignment for the 0x0000-0x7FFF 128KB FlashROM divided into eight zones (Bank) Address Assignment for the 0x8000- 0xBFFF in order to enable the 8051 to access the entire 128KB and 128KB of RAM space of FlashROM space, two built-in CPLD register RamBankReg and used to store high FlashRomBankReg Address
