Q4 The binary data 10000110000 is ______ after AMI and HDB encoding

What is the result of the binary data 10000110000 after AMI and HDB encoding?

The binary data '10000110000' would become '+0000-+0000' after AMI (Alternate Mark Inversion) encoding, and '+000+-+-00-' after HDB3 (High-Density Bipolar 3) encoding. These are specific encoding techniques utilized in telecommunication systems to enable error-free and efficient data transmission.

AMI Encoding:

AMI encoding is a bipolar encoding rule where binary 0s result in 'no change', and binary 1s correspond to changes in the level of voltage. This technique is used in telecommunication to ensure the integrity of data transmission. In the context of the binary data 10000110000, after AMI encoding, it transforms into '+0000-+0000'.

HDB3 Encoding:

HDB3 encoding stands for High-Density Bipolar 3 encoding. It replaces sequences of four zeros with particular sequences to prevent more than three consecutive zeros from being sent. This method helps in maintaining synchronization between the transmitter and receiver, reducing the likelihood of transmission errors. In this case, after HDB3 encoding, the binary data 10000110000 becomes '+000+-+-00-'.

Understanding these encoding techniques is crucial in ensuring the accuracy and efficiency of data transmission in telecommunication systems. By implementing AMI and HDB3 encoding, organizations can achieve error-free communication and enhance the overall performance of their networks.
