12. Give an example ofa 4-bit error (ie., 4 bits are changed in the message) that would not be detected by two-dimensional parity, as illustrated in Figure 2.14. What is the general set of circumstances under which 4-bit errors will be undetected? You can do this in handwritten form, but please write and scan it neatly so that columns line up, etc. (5 points) Original Transmission Prity 01010011 1101001 0 10111101 0001110 1 0110100 1 Bits Data Parity 11 110110 Byte Figure 2.14
