A Unified Method for the Reconstruction of Sampled Data
IEEE Transactions on Computers, 1973Many digital systems have need for continuous-type output for oscilloscope display, process control, or hybrid computation. This paper presents a generalization and unification of the theory of extrapolation and reconstruction of sampled data. This generalization allows implementation of a recursive algorithm or digital filter in conjunction with the ...

Hankel norm of sampled-data systems
IEEE Transactions on Automatic Control, 1995Summary: We generalize the concept of Hankel norm for purely continuous-time systems to sampled-data systems. The Hankel norm of a sampled-data system is defined by taking into account the intersample behaviors. The formula of the Hankel norm of a sampled-data system is given by a hybrid state-space model approach. We show that the Hankel norm is equal

Interpolation and extrapolation of sampled data
IRE Transactions on Information Theory, 1956This paper is essentially an extension of the optimum filtering theory of Zadeh and Ragazzini to the case where the time function to be operated upon is available only at a sequence of sample instants. As in the latter paper the signal is taken to consist of two parts, one being a polynomial p(t) with unknown coefficients and known maximum degree n ...

Advances in computer-based control systems require to consider digital controllers on the base of multirate and unconventional sampling schemes. The purpose of this paper is to extend the concepts of system passivity which are well known ideas in the context of continuous and discrete time systems to the case of sampled-data systems.

The notion of zeros of sampled-data systems is introduced in the lifting framework so that from the continuous-time viewpoint the zeros have signal transmission blocking properties. A characterization of all such zeros is given in terms of the eigenvalues of a bounded operator on the state space.

Part 1 of the JPEG2000 standard specifies a comparatively rigid set of transformations which are applied to the image samples to produce quantized subband sample indices; the quantization indices are then passed to the block coder. The various transformations are identified in Figure 10.1, which also indicates the major parameters which are available ...

In Section 10.3.4 we showed how every subband sample may be associated with a unique location in the original image. JPEG2000 defines a variety of partitions and uses this association to map the partitions from the image domain into each of its subbands.

Having studied the separate components of a data acquisition system, we now consider the errors which are inherent in all sampled data systems. These are sampling and quantization errors. They can be reduced, but not eliminated. Examples of the design of complete systems are considered in which these errors are reduced to a level which is tolerable for
