Hello, I need help with two Tasks for Data Communication
Task 1:
Task 2:
Note: In Task 1, Figure 2, point (1) can be skipped, so only (3), (4) and (6).
I already got an answer to this question, but forgot to mention that in Task 1, Figure 2 point (1) needed to be skipped as my Lecturer said we don't have to do i
I have to submit this via PDF or Word file.
Looking forward to your reply. I will need to scan it afterwards and attach it in Word. So, I hope you can help me and do those 2 Tasks for me and please read the 'Note' I've written above about Task 1, Figure 2 where you can skip point (1) and only do the other three, (3), (4) and (6).
Thank you for your help!!!

Task 2: Error Detection and Correction: Cyclic Redundancy Check Consider the Cyclic Redundancy Check (CRC) example shown in your lecture. Suppose that the 4-bit generator (G) is 1001, that the data payload (D) is 10011111 and that r=3. a) What are the CRC bits (R) associated with the data payload of D = 10011111, given that r=3? b) Add the obtained CRC bits with the payload and check whether the receiver has detected an error or not?
