The paper addresses the problem of reconstructing a signal
at some high sampling rate from a set of signals sampled at a
lower rate and subject to additive noise and distortion. A set
of periodically time-varying filters are employed in reconstructing
the underlying signal. Results are presented for a
one-dimensional case involving simulated data, as well as
for a two-dimensional case involving real image data where
the image is processed by rows. In both cases, considerable
improvement is evident after the processing.
