Abstract : For an output series of a harmonizable process, assumed to be the result of a linear filter, it is desired to obtain the input series. Precise conditions under which this is possible are described for polynomial (and integral) filters. An extension of the Kotel'nikovShannon formula for sampling harmonizable processes is given. The inversion is illustrated on an acoustic data with a sixth order polynomial filter in detail.
