Which error detection method can detect a single-bit error?(a) Simple parity check(b) Two-dimensional parity check(c) CRC(d) ChecksumI had been asked this question in an interview for job.The question is from Parity Generators/Checkers topic in portion Combinational Circuits of Digital Circuits

Answer»

Correct ANSWER is (b) Two-dimensional PARITY check

Best explanation: A single-bit ERROR can be detected by using two-dimensional parity check method. SINCE it converts the 4-bit number into 8-bit and COUNT the number of one’s.
