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 bharat at arithos dot com Regards Bharat Pathak Arithos Designs www.Arithos.com DSP Design Consultancy and Training Company.> >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) forthis>min fs.

Just curious, how did you get a complex time signal? Are you using Hilbert transform? James www.go-ci.com
