We shall see later that the ideal filter, which would introduce no attenuation of input signals falling within the passband, and infinite attenuation of signals in the stopband, is not attainable in practice.

Walter Kikuth,Franz Grosse-Brockhoffroblem is that of predicting the future of a random signal as accurately as possible. Not surprisingly, we shall find the earlier discussions of random signals (especially section 5.4) and linear systems (especially section 7.4) useful; and to these will be added some new perspectives in the processing of random signals and noise.
