In summary, the conversation is about representing a binary word as different types of encoding, specifically RLL (2,7). The individual is having trouble with this step and is seeking assistance. The suggested solution is to refer to an article, located in the middle of the page, about RLL (2,7) encoding for magnetic storage. It is noted that the encoding is done at the sector level and may require extra bits at the end to match allowed data patterns. The encoder adds these extra bits, while the decoder ignores them.

Hello, I am trying to represent a binary word as different types of encoding. I am OK with all the different forms apart from the last one.
That last step is to represent it as RLL(2,7). However I do not know how to do it. After researching on the internet, it seems very complicated to do this.
Is anyone able to help out with this ?

Thank you kindly for any assistance.

Best article I could find. Scroll down to mid page for RLL (2,7) information. Since the encoding is done at the sector level, usually 512 bytes, there may be some extra bits at the end in order to match the allowed data patterns. The encoder adds the extra bits and the decoder ignores the extra bits:

1. What is a run length limited (2,7) code?

A run length limited (2,7) code is a type of data compression technique used in digital communication systems. It is used to reduce the amount of data needed to transmit a message, without losing any important information.

2. How does a run length limited (2,7) code work?

A run length limited (2,7) code works by encoding a sequence of bits into a shorter sequence of bits, using a predefined set of rules. It replaces longer sequences of repeated bits with shorter codes, thus reducing the overall length of the message.

3. What are the advantages of using a run length limited (2,7) code?

The main advantage of using a run length limited (2,7) code is that it allows for efficient data transmission and storage. It can significantly reduce the amount of data needed for a message, without compromising the integrity of the information being transmitted.

4. What are the limitations of a run length limited (2,7) code?

One limitation of a run length limited (2,7) code is that it is only suitable for certain types of data, such as binary data or images with large areas of uniform color. It may not be as effective for data with more complex patterns or variations.

5. How is a run length limited (2,7) code different from other types of data compression techniques?

A run length limited (2,7) code is different from other data compression techniques, such as Huffman coding or Lempel-Ziv-Welch (LZW) coding, because it specifically focuses on reducing the length of runs of repeated bits. Other techniques may use different methods, such as dictionary-based compression or statistical analysis, to achieve compression.
