Assuming we are using the error detection coding---parity coding, the channel error is bursty (meaning if there is error, one or two adjacent bits will be flipped). For the received sequence '010101001000', the last two bits '00' are parity bits (the first 0 protects the odd bits, the second 0 protects the even bits). (a) How many bits are in error? (b) What bits are in error?
