Time Division Multiplexing  Synchronous & Statistical?
Can someone pls tell me what are they used for & whats the differnece between their characteristics? :nonod:
Thanks :happy:

hey thanks for the link
you come to my rescue again :D 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 10101. The receiver receives the following bit pattern: 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 :D 
Re: Time Division Multiplexing  Synchronous & Statistical?
I think you are right :smile:
Code:
*** I hope it's correct :thinking: I get the output as 10100101011 
Re: Time Division Multiplexing  Synchronous & Statistical?
yeah... same ans as yours :D
how i wish you can go for the exams for me haha ;) 
Re: Time Division Multiplexing  Synchronous & Statistical?
:biggrin: .. LOL .. :rofl:
Best of luck for your exams.. :wink:

Hi Saswapadhi 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? :nonod::nonod: 
Re: Time Division Multiplexing  Synchronous & Statistical?
OK, I'll go through it and try to answer to the best of my knowledge :smile:

Re: Time Division Multiplexing  Synchronous & Statistical?
oh thanks my saviour! will wait for ya! :)

Re: Time Division Multiplexing  Synchronous & Statistical?
OK, I read the question .. it's pretty straight forward :
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 3bit 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.
