- Question
Error rate is
Options- A. an error-detecting code based on a summation operation performed on the bits to be checked.
- B. a check bit appended to an array of binary digits to make the sum of all the binary digits.
- C. a code in which each expression conforms to specific rules of construction, so that if certain errors occur in an expression, the resulting expression will not conform to the rules of construction and thus the presence of the errors is detected.
