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:
