A MAC Frame format has a Preamble of 7 octet pattern in the form of alternating 1s and 0s used by a receiver to establish synchronization. Use a Manchester Encoding technique to describe the first octet of the signal pattern produced within the Preamble.

The answer is "10101010".  

Explanation:

Description of the above question as follows:

Encryption with Manchester is a bit transmission method that makes synchronizing the receiver with the sender simple. It splits each bit time frame into two, ensuring that the signal levels are always transient in the middle of each bit.The encoding of Manchester explains the first byte of the frequency signal pattern, which produced in the preambles which are given in the attachment.
