I'm stuck on the following question that I am trying to use for revision purposes. The question states that the data transmitted is 1001101, however, during transmission the second bit has an error and is received as 1 instead of 0, thus the data is 1101101. I need to use the hamming code to detect this error, however, when doing so, my p1, p2 and p4 values are all equal to 1, giving me 111 and indicating an error with bit 7.
Can anyone please help point me in the right direction? I am new to this so apologies if the error is staring me right in the face.
Thanks in advance for any help.
