- Under the Binary Convolutional Codes for a 100-bit codeword how many check bits are needed? What is the code rate in this example?To what extent may a message's parity bits be used to detect errors?"Rabenstein code was used to send a message with 4 information bits, you receive 100110001 , if you can expect at most one bit of corruption, what were the original information bits?
- Given the codeword=01110101111101010, find if it has an error bit or none. If it has an error bit, indicate the bit position. Data message has 12 bits.One way of detecting errors is to transmit data as a block of n rows of k bits per row and adding parity bits to each row and each column. The lower-right corner is a parity bit that checks its row and its column, Will this scheme detect all single errors? Double errors? Triple errors?The bitstring 1011110 and 0100001 were subjected to XAND. What is the result?
- Please provide assistance with the following question: When it comes to parity bits, what is the maximum number of mistakes that may be detected in a message?When bit stuffing is used, is it possible for the loss, insertion, or modification of a single bit to cause an error not detected by the checksum? If not, why not? If so, how? Does the checksum length play a role here?The following bit patterns were originally encoded using even parity. In which of them have errors definitely occurred? 10100101 01111010 10001010 01010000 11110011
