However, since it reduces the error, especially in Analog-Digital converters,

It is a highly preferred code in devices.

CONVERSION OF BINARY NUMBERS IN GRAY CODE

Binary numbers are converted to Gray code;

a) The highest valued (MSB) bits are subtracted.

b) Every bit is added to the right bit regardless of hand.

c) This process continues until the lowest-valued (LSB) bite.

d) The number obtained is the Gray code equivalent of the binary number.

Note: If it is desired to convert Decimal Numbers to Gray code, Decimal Count must first be Binary There is a provision.

Sample:

Convert the following Decimal numbers to Gray code.

Solution:

(45) 10 = Binary rate of the number of GRAYs

(45) 10 = (101101) 2.

Step 1 Create the first digit of the MSB Gray code with the highest-valued bit.

1 0 1 1 0 1 Binary

1 Gray

II.Adim The bit to the right of the highest-valued bit is added irrespective of the hand.

1 + 0 1 1 0 1 Binary

1 1 Gray

III. The step collection operation continues for the next bits

1 0 + 1 1 0 1 Binary

1 1 1 Gray

IV. The step collection operation continues for the next bits

1 0 1 + 1 0 1 Binary

1 1 1 0 Gray

V. The step collection operation continues for the next bits

1 0 1 1 + 0 1 Binary

1 1 1 0 1 Gray

VI. The picking process continues until the lowest valued item

1 0 1 1 0 + 1 Binary

1 1 1 0 1 1 Gray

Conversion process completed

(45) 10 = (111011) GRAY

CONVERSION OF GRAY CODE NUMBERS TO INSTITUTIONAL REVENUES

Gray Coded Numbers Binay (Dukilik) Numerical conversion;

a) The leftmost bit is accumulated regardless of the next digit.

b) The sum of the total result and the next number is accumulated irrespective of the hand.

c) This process is continued until the rightmost step.

LOGIC CONSTRUCTIONS

ACCURATE TABLES

Truth tables are the simplest and most useful for designing and analyzing digital circuits. method. For all possible cases where the input variables of the truth table can be output tablature In an accuracy table, if n number of entries Variable these variables can take on a variable number of possible values. For example, a digital (n = 2) input variables, the number of states that these variables can take is 22 = 4, three input variables (n = 3) for 23 = 8 different states can be written.

LOGIC DOORS

AND DOOR

An exit of the AND gate has two or more entry lines. In Figure 3.1 there are two entries, one entry The symbol of the VE door, the accuracy table and the electric equivalent circuit are given.
