Question

$\text{The most suitable coding scheme for coding the successive position in an 8-position digital}\text{shaft encoder is}$

• A. $\text{BCD coding}$
• B. $\text{4321 coding}$
• C. $\text{Gray coding}$
• D. $\text{Excess-3 coding}$

Answer 1

The correct option is C $\text{Gray coding}$

$\text{For a digital shaft encoding the maximum change in the two alternate position is unity, thus}\text{gray code is most suitable for digital shaft coding}$
