A. 产生一个长为1000的二进制随机序列，“0”的概率为0.8，”1”的概率为0.2；B. 对上述数据进行归零AMI编码，脉冲宽度为符号宽度的50%，波形采样率为符号率的8倍，画出前20个符号对应的波形（同时给出前20位信源序列）；C. 改用HDB3码，画出前20个符号对应的波形；D. 改用密勒码，画出前20个符号对应的波形；E. 分别对上述1000个符号的波形进行功率谱估计，画出功率谱；F. 改变信源“0”的概率，观察AMI码的功率谱变化情况；-have a length of 1,000 random binary sequence, "0" with a probability of 0.8, "a" with a probability of 0.2; B. above zero AMI data coding, and pulse width of symbols width of 50%, waveform sampling rate Symbol rate for the eight times that he painted before the 20 symbols corresponding waveforms (also given before 20 Source sequence); C. HDB3 code switch to depict the former 20 symbols corresponding waveform; D. Miller to switch codes to depict the former 20 symbols corresponding waveform; E. respectively above 1,000 symbols for the power spectrum waveform estimated to depict the power spectrum; F. Change source "0" the probability to observe AMI code changes in the power spectrum;

WDM驱动程序设计　　 一．WDM简介 　　微软不断推出新的操作系统，现在Windows98和Windows2000已经成了主流，原先用来实现驱动程序的VxD技术随着Win95的淡出也慢慢地将退出历史舞台，在Windows98和Windows2000中设备驱动程序将根据Windows驱动程序模型（WDM）来设计。WDM通过提供一种灵活的方式来简化驱动程序的开发，在实现对新硬件支持的基础上减少并降低所必须开发的驱动程序的数量和复杂性。 -WDM Driver Design 1. WDM briefed constantly introduce new Microsoft operating system, now Windows 98 and Windows 2000 has become mainstream. originally used to achieve the VxD driver technology with the Windows 95 are slowly fade out to be from the historical stage, in Windows 98 and Windows Device Drivers under Windows Flooding dynamic process model (WDM) to the design. WDM by providing a flexible way to simplify driver development, the realization of new hardware support on the basis of the reduction and cut the need to develop drivers for the number and complexity.
