Invented by Emile Baudot (1845-1903)
• Originally called a "cyclic-permuted" code
• Telegraph - 5 bit codes
- Bits stored on a code wheel in the receiver
- Wheel connected to the printing disk
- Matched pattern on wheel and received pattern and
then actuated head to print.
• Exhibited at Universal Exposition, Paris (1878)
The reflected binary code, also known as Gray codeafter Frank Gray, is a binary numeral system where two successive values differ in only one bit.Here is an example of a 4-bit Gray code:0000000100110010011001110101010011001101111111101010101110011000
gray code is reflective because 9's complement of any number and 1,s complement of code is same i.e 0 reflect 9 1 reflect 8
The Morse Code was invented because we can send messages to each other like s.o.s
A student Bernie overheard a conversation and told his teacher Woodland about it and he experimented and he invented the bar code using morse code.
In 1679
Gray Code is Reflective Binary code. One of the main disadvantages of Gray code is that it is very difficult to come up with an arithmetic logic unit to support Gray code.
characteristic of Gray code
The Gray Code is a type of binary code developed by a programmer named Frank Gray. Gray code is a binary numeral system that differ than normal binary code, and is used widely to detect errors in software.
The airport code for Gray Army Airfield is GRF.
The Code of Marcia Gray was created on 1916-03-16.
colors cant be invented
Gray code
help PLA use convert excess-3 to gray code
Gray code is a 'reflected code', why is it named so will be illustrated soon. The advantage of Gray code over binary code is that only one bit in the code group changes when going from one number to the next. By, Ashish Kumar (Roh, Nawada, Bihar)
