you come to my rescue again

i having alot of problems in my assigments can you check if i did the following correctly?

Consider a transmission system using Cyclic Redundancy Check (CRC) technique with a

generator polynomial

generator polynomial

100111011000.

(a) Draw a digital logic circuit for a shift register implementation of CRC.

[8 marks]

so supposed i am supposed to place the XOR circuit to the right of any position for which the associated value for P(X) is one, i think it should be

A <---B + C <---D +

Can you help me out on this? thanks

I think you are right

(* means a joint, + means XOR).

I hope it's correct

I get the output as**10100101011**

Code:

*----------------*------------------* | | | \_/ \_/ | *-- A -----> B --+--> C -----> D ---+-<-- Input

I hope it's correct

I get the output as

i have one more question but its hard to state the whole question here

I attached my tutorial... its question 2... can you explain to me what is bit sequence? and what r they actually asking?

OK, I'll go through it and try to answer to the best of my knowledge

oh thanks my saviour! will wait for ya!

For each of the periods (1 to 8), just check the amplitude of the waveform, and its phase difference with respect to the previous period. Then write the 3-bit symbol from the table, corresponding to it.

E.g., for the first period, the symbol is 001, 'cuz amplitude is A2 and phase difference is 0.

for the second period, the symbol is 010, 'cuz amplitude is A1 and phase difference is 1/(4f).

I won't complete the answer 'cuz that would be a spoiler. Try it yourself and if you can't then I'll try to post complete answer.
