hi,i want to thank u for your help,am very thankfull,
now i think got to knw how to draw the frequency analysis by using spectrum analyzer,
As you knw am running out of time ,only few days left for my project to b delievrd n disscused*,
anyway i'm trying to input an NRZ signal(by using bernoulli block+unipolar to bipolar converter) to a phase locked loop .
nrz>>>raised cosine filter>>>square(nonlinear)>>>pll
i've built the pll n the nrz bt still un able to connect the rest of the circuit .
my project is called ((bit synchronizer))
plz help me if u can
Regards,
Ahmed

Hi mohnnad
i'm bothering u with my questions,but am really running out of time,i didnt expect any1 to reply on my subject.
thank u very much.
now as i told b4
am trying to build a bit synchronizer using matlab simulink
my prof. plan is to connect
nrzlevel signal(nrzl) >>>raised cosine filter>>>squar the signal in somehow>>>pll(phase locked loop)
i've desinged the pll .bt it's really hard to connect the rest
by the way the frequency of the nrz should be equal to (10khz)
thank u for ur help
Regards,
Ahmed
