| Description
| - Návrh dvoukanálové banky číslicových filtrů s perfektní rekoctrukcí. Banka je odvozena ze základního filtru tyou dolní propusti a přenosem H0(z). Tento filtr definuje záklaní impulzní charakteristiku a určuje vlastnosti celé banky filtrů. Dvou a více kanálové banky jsou často používány zejména v telekomunikacích, kompresi signálů a jejich extrakci ze šumu. Banky jsou často spojeny s vlnkovou transformací. (cs)
- The paper deals with the optimization of the criterial function of a two-channel bank of digital filters with perfect reconstruction (PR) and with limiting conditions given by the required frequency processing of the input signal. The bank of digital filters has been derived from the basic low-pass filter with transfer function H0(z). This filter defines the initial impulse characteristic and, at the same time, determines the properties of the whole bank. The functionality and universality of the given approach of the optimum design are demonstrated on several typical examples. Genetic algorithms are used for the selection of correctly conditional initial optimization conditions. Two- and multi-channel banks of digital filters are used frequently, in particular in telecommunications in signal compression and its extraction from noise, in communication technology, in biomedicine, etc. These filter banks are often associated with the wavelet transform, which defines directly individual impulse character
