Why Gray coding is used in K-map?

Why Gray coding is used in K-map?

Error probability is reduced. This property is used in K-map to simplify Boolean functions. You can identify adjacent 1s or 0s and reduce it. The cells in a K-map are numbered in Gray code so that only one bit is changed and you can take variables of consecutive cells in common to cancel out the varying bit.

Why Gray coding is used in K mapping instead of binary?

Because Gray code only changes one bit at a time as you move between adjacent states, so it makes the groupings of terms possible, because they’re next to each other. If you used binary code, the regions would be disjointed and the grouping of terms not obvious.

Why is Gray code used?

Gray codes are widely used to prevent spurious output from electromechanical switches and to facilitate error correction in digital communications such as digital terrestrial television and some cable TV systems.

Why is Gray code called Gray code?

The reason for calling this code as reflected binary code is the first N/2 values compared with those of the last N/2 values in reverse order. In this code, two consecutive values are differed by one bit of binary digits.

Which code is used in K-map Why?

K-maps are a visual representation of a Boolean function. K-maps contain cells corresponding to each minterm for a function. The ordering of these cells is done using the Gray code (00, 01, 11, 10) in order to show adjacency between cells. In other words, each cell’s neighbor has only one differing bit between them.

Why the row and column numbers of the K-map are assigned in Gray code rather than binary numerical order explain in brief?

Because B+B’=1. To utilise this concept of B+B’=1 easily we have Gray code in K-Map. When we have a difference of 1 bit b/w two adjacent cells we can easily eliminate Redundant literals from the expression & then we can minimize our function which is the aim of K-Map !

Why is the Gray code more practical to use when coding the position of a rotating shaft?

Explanation: The Gray code is more practical to use when coding the position of a rotating shaft because only one digit changes between counts that is reflected to the next count. Reflected binary codes were applied to mathematical puzzles before they became known to engineers.

What is gray code and mention its advantages?

In Gray code, if we go from one decimal number to next, only one bit of the gray code changes. Because of this feature, an amount of switching is minimized and the reliability of the switching systems is improved. Advantage of grey code over binary is only one-bit changes for each step.

Why is GREY code so important in digital design?

Gray codes are very useful in the normal sequence of binary numbers generated by the hardware that may cause an error or ambiguity during the transition from one number to the next. So, the Gray code can eliminate this problem easily since only one bit changes its value during any transition between two numbers.

Why Gray code is called reflected code with example?

The Gray code is sometimes called a reflected code because the bit values are reflected on both sides of any 2″ value. For example, as shown in Table 3-5, the values of the three low-order bits are reflected over a line drawn between 7 and 8.

What is Gray code and its applications?

Gray Code system is a binary number system in which every successive pair of numbers differs in only one bit. It is used in applications in which the normal sequence of binary numbers generated by the hardware may produce an error or ambiguity during the transition from one number to the next.
