An error correcting code has the following code words: 00000000,00001111,01010101,10101010,11110000. What is the maximum number of bit errors that can be corrected? 0 1 2 3 Minimum hamming distance is 4 Error detection is dmin-1= 4-1=3 Error correction is 3/2 =1.5 ie 1 floor of it Then why answer key shows answer 3... Please help

Sixteen-bit messages are transmitted using a Hamming code. How many check bits are needed to ensure that the receiver can detect and correct single-bit errors? Show the bit pattern transmitted for the message 1101001100110101. Assume that even parity is used in the Hamming code. My Solution:- But Correct answer is :- 011110110011001110101 I don't know what i am doing wrong ?
