Sr. Pillai et B. Elliott, NEW RESULTS ON THE RECONSTRUCTION OF BAND-LIMITED SIGNALS FROM PAST SAMPLES, Electronics Letters, 29(17), 1993, pp. 1501-1503
A new technique that makes use of only the past sample values of a ban
dlimited signal for its reconstruction is presented. It is shown that
any bandlimited signal can be reconstructed from its past samples alon
e, provided the sampling rate is at least twice the minimum required N
yquist rate.
