Abstract :
For a stationary bandlimited process sampled at periodic times t/sub n/=nT, exact reconstruction is possible when the spectral band is (-/spl pi//T, /spl pi//T). We give a proof of an exact formula (the Lagrange interpolation formula) when the sampling set is a mixture of periodic times.
