Depicts the use of a duobinary conversion filter for the transmission of binary data bit stream through a band-limited channel. The following bit mapping operation is implemented in the PAM: a_k = {+ 1, b_k = 1 -1 b_k = 0 Determine the relationship between the output sequence {y_k} and the data pulse sequence {a_k}. Determine the decoding rule based on the sequence {y_k} sampled at the output of the duobinary conversion filter. (c) Consider the transmission of the data bit stream {0 0 1 1 0 0 1 1 0 1 0 0 1 1 1 0} with the initial bit (0) being the reset but not a data bit. Tabulate the data bit stream the transmitted pulse sequence {a_k}, the sampled filter output sequence {y_k}, and the decoded sequence {b_k} using the same table format found in a pertinent example in Lecture Notes #7.

Solution

bit stream is a contiguous sequence of bits, representing a stream of data, transmitted continously over a communications path, serially (one at a time).
