delay lock loop in matlab

[nidahas]

hi to all,
i have to implement delay lock loop in matlab/simulink for fm demodulation.if you people can please guide me from where to start.
i ll really apreciate your help
thanks alot!

check this page , there are alot of info about DLL , wich this help u

**broken link removed**

[nidahas]

thnx alot.but i cant really find anything on DLL in simulink!

 

[khouly]

u need to create things by urself

[nidahas]

its not that i am asking u ppl to spoon feed.i m sorry if i gave that impression.i just needed some basics.sorry again

 

[khouly]

i didn't mean , that u ask for a spoon feed ,
i know that there is no model for the DLL in simulink like PLL , so i am just stating , that u need to create the voltage controlled delay emelent and the edge combiner

that's it

i am looking and trying to implement it.its just that i ve to start from the basics.and i couldnt really find the fundamentals anywhere regarding the fmdeodulation using dll.
thanks alot for all your help.

yeah , most of the FM demodulation is carried out with the PLL in the phase a frequency domain , and the DLL in the modulation is new , so it is hard to find these things , but really it is an interesting work .

u need to analyze the DLL in the phase domain , so u need to convert the voltage control delay line to a phase relation , and then analyze the system like PLL analysis wise
