进入MatLab程序运行界面后，运行程序，界面会出现请输入NRZ玛，输入方式按数组方式输入，确认输入的NRZ码之后，程序会自动输出 CMI，AMI，HDB3的编码和解码的结果，可以清晰的对照出编码前后的结果。-into MatLab interface operating procedures, operating procedures, the interface will enter emerging NRZ Mary, by the array input mode input and confirm the NRZ, the program will automatically output CMI, AMI, HDB3 encoding and decoding, the results of which will clear up the control of the results before and after encoding.
