Error detecting and correcting codes are based on significant distance between two bit strings in terms of the number of bits that have to alter to get from the first ...

What is CRC-4 (Cyclic Redundancy Check 4)? CRC-4 (Cyclic Redundancy Check 4) is a form of cyclic redundancy checking -- a method of checking for errors in transmitted data -- that is used on E1 trunk ...

This application note describes how to use the enhanced error detection cyclic redundancy check (CRC) feature in the Arria® II, Stratix® III, Stratix IV, Arria V ...

You send a file, but how do you know it arrived intact? In other words, how do you know that it didn’t get cut off, garbled, or changed somehow? Simplistically, you could just add up all the bytes in ...

This may seem like a very complicated way of thinking about a very simple code, but it opens up the possibility of constructing more advanced codes. For example, the key to the parity checking code is ...

Including transistor-level implementations, this comprehensive book offers a friendly presentation of the fundamental principles and practices of modern digital design, as well as complete, realistic, ...
