Hypermine-Logic Minimization Application written by the author will be utilized for performing minimization of four logic functions: adder/subtractor, comparator, multiplier and square rooter from 4 up to 16 input variables. An exclusive-OR transformation of the higher half of the input variables will be applied in the second round of minimization of the specified functions. It will be pointed out that XOR transformation significantly reduces number of generated minterms but only with additive and comparator functions. Transformation has small effect on multiplier and opposite effect on square root function.","PeriodicalId":253344,"journal":{"name":"5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service.

Next-generation TTS systems will have to convert machine-readable text into audible speech using different approach. The aim of research in this field is to increase the naturalness of speech synthesis significantly while maintaining good intelligibility. Synthetic realistic mouth motions matching the speech sounds not only give the perception that the image is talking, but can actually increase the intelligibility of the speech (increased redundancy). Also, there is a psychological moment: animated images (agents, avatars, virtual personae) can increase a user's patience while waiting on searches and database retrievals. The newest advance in the visual TTS (VTTS) is given.","PeriodicalId":253344,"journal":{"name":"5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service.

Starting from the characteristics of the second-generation cellular systems and the required next-generation features, different possible migration paths towards next-generation systems are analysed. Thus, two basic scenarios - evolutionary and innovative - are described. However, it is shown that considerable modifications in this basic approach can be introduced. A full scale of possible third-generation deployment possibilities is identified. The presented analyses are then used for defining an algorithm for the choice of an optimized solution.","PeriodicalId":253344,"journal":{"name":"5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service.
