Suppose we want to transmit the message 1011 0010 0100 1011 and protect it from errors using the CRC-8 polynomial x8 + x² + x¹ + 1. (a) Use polynomial long division to determine the message that should be trans- mitted. (b) Suppose the leftmost bit of the message is inverted due to noise on the trans- mission link. What is the result of the receiver's CRC calculation? How does the receiver know that an error has occurred?

How many bits a sender append to this information before computing CRC code word? b. compute the CRC code word for the information word 101101001 C. Check the division performed at the receiver with the cord word of the result of b. d. If a receiver received a code word, 1011011001010112, does an error in the transmission of information? (Show your work.)
Demonstrate by example (write down a few dozen arbitrary bit patterns; assume one start bit and a stop element of length one bit) that a receiver that suffers a framing error on asynchronous transmission will eventually become realigned.
In the following situation, kindly mention whether or not there was a mistake made. The number "001011010" is sent to the receiver by the sender. The devices make use of an odd parity, an eight-bit data, and a one-bit (LSB) parity for each bit of data respectively. What results may we anticipate if the devices make use of even parity as opposed to odd parity? What kinds of communication protocols are used by TESLA automobiles? Provide the schematic for the one or ones that you have discovered.
