Answer #1
  • In 8 bit checksum, the data unit to be transmitted is divided into segments of 8 bits.
  • All the 8 bit segments are added.
  • Additional bits are wrapped and sum is performed again
  • The result of the sum is then complemented using 1’s complement arithmetic.
  • The value obtained is called as checksum.
  • Here the checksum value is 10001000=0x88

Design an even parity detection circuit. A parity bit is an error checking mechanism. Your circuit will count the number of 1’s in a stream of bits. If the number of 1’s is even, the circuit turns on an output called Y. Assume a single bit at each cycle – call the input X. Do not use an accumulator or counter. Design the even parity detection circuit using J-K flip-flops. Your answer must include: a. The state diagram. b. The...
