APPROXIMATION OF LOWPASS FILTERS WITH FREQUENCY-DEPENDENT INPUT GAIN CHARACTERISTIC.

An approximation method is described for the design of lowpass filters where the input stage has a frequency-dependent gain characteristic. These filters are used in speech processing systems. The proposed method, being closed-form solution, is more reliable and requires much less C. P. U. time compared to the previously used methods. The developed algorithm can be incorporated into any suitable general synthesis program

Analysis of pulse propagation on high-speed VLSI chips

A new method is presented for the analysis of interconnections on high-speed LSI/VLSI chips. Interconnections are treated as lossy multicon-ductor transmission lines with nonlinear terminal loads. The technique can be generalized for analysis at the system level

Error Probability for Multilevel Digital Systems in Presence of Intersymbol Interference and Additive Noise

Generalization of a recently published technique for the evaluation of error probability in fiber-optic communication systems is described. The crux of the method is a minimax approximation of the cumulative distribution function of the additive noise. The additive noise is not constrained to be Gaussian. Examples and comparisons with previously published techniques are presenteb

Analysis of Pulse Propagation on High-Speed VLSI Chips

A new method based on a piecewise decomposition technique is presented for the analysis of interconnects on high-speed LSI/VLSI chips. Interconnections are treated as lossy multiconductor transmission lines with arbitrary nonlinear terminal loads. The technique can be generalized for analysis at the system level. 0018-9200/90/0400-0490$01.0

Production control in the food processing industry: The need for flexibility in operations scheduling

Analyses the problems of production scheduling in the dairy product industry where variety and sell-by date constraints have to be taken into account. Using the formalization of priorities as a basis, attempts to demonstrate that a thorough understanding of the relation between a formal scheduling model and its implementation permits one to grasp the profound changes in industrial processing systems at present. With this analysis new representations of possible changes can be created and the idea of a transformation of work organization based on a new form of production management can be developed
