Bit stuffing is one coding technique for preventing patterns from occurring in data. The code rate for bit stuffing is always less than the Shannon capacity.

Converting Gray Code to Binary1). Write down the number in gray code.2). The most significant bit of the binary number is the most significant bitof the gray code.3). Add (using modulo 2) the next significant bit of the binary number to thenext significant bit of the gray coded number to obtain the next binary bit.4). Repeat step 3 till all bits of the gray coded number have been added inmodulo 2. The resultant number is the binary equivalent of the gray number.Converting Binary to Gray Code1).

After a bit of digging - that is a mobile (cell) number originating in america. 001 is the IDD code for america.... 415 is the code indicating a cell-phone.
characteristic of Gray code
When going from one number to the next in Gray Code 1 bit only ever changes, whereas with binary more than 1 bit could change.
7 bits can make 128 distinct codes.
In weighted codes, for each position(or bit),there is specific weight attached.For example,in binary number,each bit is assigned a particular weight 2n where n is the bit(or position) number for n=0,1,2,3,4 and the weights are 1,2,4,8,16 respectively.
you need thee extra bit for 4 bit data in hamming code.
In the office room with the computer without keyboard. If you wait just a bit, the screensaver will come on. And the screensaver is your answer "C : 8008"
An 8 bit binary code is a code that is 8 digits long. It would look like this: 00110010
