Opis:: Envelope constrained filter design is concerned with the time domain synthesis of a filter whose response to a specified input signal stays within prescribed upper and lowe bounds and in addition has minimal noise enhancement. In many practical applications, a "soft" approach, such as least mean square, is not the most suitable and it becomes necessary to use "hard" constraints such as the ones considered in the paper. We present an overview of key ideas related to robust continuous time envelope constrained filter design.

Opis:: The current-voltage characteristics (I-V) of non-stoichiometric bismuth tellurite crystals were studied in a range of temperatures from 150°C to 350°C and fields up to 2.5 kV/cm with asymmetric contacts (In-Ga eutectic and Na₂SiO₃). The I-V curves and observed monopolar injection are described by the approximation of space charge limited currents. In the composition of 47% Bi₂O₃-53% TeO₂ electronic conduction is prevailed. In the composition 43% Bi₂O₃-57% TeO₂ the conductivity is contributed by electrons and holes. The spectrum of local states in the band gap of the studied crystals is quasicontinuous, which cannot be described by models of a discrete or exponential distribution.
