Добре відомо, яку виключно важливу роль відіграють в радіотехніці коливальні системи. Коливальними системами для діапазону надвисоких частот є резонатори, що представляють великий і значний клас пристроїв НВЧ. У статті проведено огляд сучасних фільтруючих пристроїв НВЧ , сучасні уявлення про їх основні властивості та методи побудови. Істотним чинником, що визначає проблеми фільтробудування є те, що перехід до інтегральних схем, що містять елементи з розподіленими параметрами, супроводжується рядом небажаних явищ: добротність, паразитні смуги пропускання і хвильові типи коливань. Дослідження показало, що оптимізація конструктивних параметрів коливальних систем таким чином, щоб змінювались їх частотні характеристики, призведе до зменшення втрат резонаторів.
It is well known that oscillatory systems play an extremely high role in radio engineering. The resonators are oscillatory systems for the ultrahigh frequency range that representing a large and significant class of superhigh frequency devices. The article provides an overview of modern superhigh frequency filtering devices, recent interpretations about their main properties and methods of construction. An important factor that defines an issue of filter composition is the transition to integrated circuits containing elements with distributed parameters which accompanied by a number of undesirable phenomena: Q-factor, parasitic bandwidth and wave types of oscillations. The research has shown that the optimization of the design factors of oscillatory systems in such a way that their frequency characteristics are changed, will reduce the losses of the resonators.
Information technology creates image restoration, providing them with limited decompression loss of quality imaging and exclude uncontrolled loss of information provided decline in ancillary data. Uncontrolled losses are eliminated as a result of the removal of the following cases: incorrect definition of the boundaries of code words that contain values applicable adaptive embedding monobasic positional numbers; false positioning coded representation related transformant; errors in the process of obtaining lengths of series of binary elements which have the primary transformant information about the components, including the low-frequency components of the spectral representation
Grounded topicality of the development of information technology and data processing technologies for improving the quality of services. It is shown that the variant of compression technology is to modify the methods of coding bitplanes. Substantiated that the future trend is to transform coding bit descriptions with preliminary identification of a series of binary elements in an adaptive monobasic positional coding. Developed a method of image compression with advanced quantization component transforms discrete cosine transform, which takes into account the embedding conditions adaptive monobasic positional coding. It is proved that in this case provided: raising the compression, with the exception of uncontrolled loss of quality of the reconstructed image due to both psy elimination of redundancy and lack of choice of service data to describe the structural component on the steps of converting the data reduction of processing time as a pre-processing step , and encoding step for reducing the redundancy.
In this paper proposed a model for evaluating the degree of reduction in the volume of video data with the limited availability of quality loss visualization images based on compression method using adaptive array monobasic positional encoding lengths of series of binary elements (CDE) of bit description transformant. Described the stages of creating the model cost estimates the number of operations for processing images with the following features: the formation of an array of lengths of series of binary elements is achieved by indexing series of binary elements in the one-dimensional sequence based on their linear coordinates; formation code for adaptive monobasic positional number in the compression bit description transformant carried out without time delays on the calculation of weights which reduces the number of multiplications; allocation of the number of discharges under the codeword implemented as a result of only one multiplication. Proposed a comparative evaluation of the proposed method with the existing methods of compression in available mode as a limited loss of visualization of images in the degree of volume of video data, that is reduced, and the time for its processing.
