| 21. | As the name implies, this type of Gray code uses non-Boolean values in its encodings.
|
| 22. | In this generalized sense, the Steinhaus Johnson Trotter algorithm generates a Gray code for the permutations themselves.
|
| 23. | The Johnson counter generates a Gray code, a code in which adjacent states differ by only one bit.
|
| 24. | For counters, Gray coding gives minimum switching activity, and thus is suitable for low-power designs.
|
| 25. | Martin Gardner wrote a popular account of the Gray code in his August 1972 Mathematical Games column in Scientific American.
|
| 26. | The bits of the Gray code of i, G ( i ), are used to select direction numbers.
|
| 27. | The example shown here is for 8-PSK, which has also been given a Gray coded bit assignment.
|
| 28. | #How many " non-trivially distinct " Gray codes of a given alphabet size and codeword length exist?
|
| 29. | Gray codes are used in position encoders ( linear encoders and rotary encoders ), in preference to straightforward binary encoding.
|
| 30. | Rotary encoders benefit from the cyclic nature of Gray codes, because consecutive positions of the sequence differ by only one bit.
