CCNA2
说明: CCNA中文笔记第2章
DoD模型被认为是OSI参考模型的浓缩品,分为4层,从上到下是1.DoD模型的Process/Application层对应OSI参考模型的最高3层
2.DoD模型的Host-to-Host层对应OSI参考模型的Transport层
3.DoD模型的Internet层对应OSI参考模型的Network层
4.DoD模型的Network Access层对应OSI参考模型的最底2层
(CCNA Chinese Notes Chapter 2 DoD model OSI reference model is considered concentrated products, divided into four layers, from top to bottom is 1.DoD Model Process/Application layer of OSI reference model corresponds to the maximum 3-layer model 2.DoD Host-to-Host layer corresponds to OSI reference model Transport Layer 3.DoD model Internet layer corresponds to OSI reference model Network model Network Access Layer 4.DoD OSI reference model layer corresponds to the bottom layer 2)

码型反变换的仿真实现
Ⅰ、基本任务:由抽样判决后的AMI码型和CMI码型数字序列恢复出原始的PCM脉冲编码信号。
主要步骤和要求:
(1)由抽样判决后的AMI码型数字序列恢复出原始的PCM脉冲编码信号(0、1信号)。要求抽样判决后的AMI码型数字序列可以是数字型也可以是字符型;要求画出码型反变换前后的波形图。
(2)由抽样判决后的CMI码型数字序列恢复出原始的PCM脉冲编码信号。要求抽样判决后的CMI码型数字序列可以是数字型也可以是字符型;要求画出码型反变换前后的波形图。
Ⅱ、选做任务:由抽样判决后的HDB3码型数字序列恢复出原始的PCM脉冲编码信号。
主要步骤和要求:
由抽样判决后的HDB3码型数字序列恢复出原始的PCM脉冲编码信号(0、1信号)。要求抽样判决后的HDB3码型数字序列可以是数字型也可以是字符型;要求画出码型反变换前后的波形图。

Fifth problem, Pattern Simulation of inverse transform
Ⅰ, basic tasks: decision by the sampling pattern after AMI and CMI pattern sequence to recover the original digital PCM pulse code signal.
Main steps and requirements:
(1) post-judgment by the AMI code sample digital sequence to restore the original PCM pulse code signal (signal 0,1). AMI requires post-judgment sampling digital code sequence can also be a numeric character asked to draw a pattern waveform before and after the inverse transform.
(2) post-judgment by the CMI sampling digital code sequence to restore the original PCM pulse code signal. Requirements of post-judgment CMI sampling digital code sequence can also be a numeric character asked to draw a pattern waveform before and after the inverse transform.
Ⅱ, choose to do the task: the post-judgment by the sample type HDB3 code sequence to recover the original digital PCM pulse code signal.
Main steps and requirements:
