Bandpass signal

Started by Aneesh_mg May 18, 2008
Hi...the working of bandpass signal is a bit confusing for me...

for example...
for a given raw signal,complex,nonzero over Wa= 10khz and Wb=15khz and
given sampled digital signal x(n)=Xa(nTs)

Need your help to deterine the min fs such that raw signal xa(t)can be
recovered from its sample x(n).

AFter that need to determine the interpolation formula for xa(t) for this
min fs.



Aneesh,

   This looks like a standard DSP textbook problem. Get hold of
   understanding DSP by Rick lyons and in that he has illustrated
   bandpass sampling and its verious types. regarding the second
   part that should be simple.

   In case if u still could not solve it, get in touch with me

Just curious, how did you get a complex time signal? Are you using
Hilbert transform?

He got it grom his professor. It doesn't display very well on his 'scope. Jerry
