(data communication)

please guys help me quickly

i need to solve this question.

Last signal element +5V was in(-) pole OV (Amount of "1" bits -5V sent after last violation is EVEN) a. The receiver has already decoded the previous part of the received signal encoded by using Bipolar-AMI+HDB3. For the signal given below, answer the following questions: Extract data from the signal. If there is error in the received signal, explain how you detected the error and get data up to error part. (20 p) b. If the modulation rate of a signal encoded as NRZI and having the same modulation rate as above signal is 24 Mbaud, what are the date rate and total transmission time of above signal?
