The Fourier Transform

In the past few years on-line digital television frame store devices coupled to computers have been employed to attempt to measure the microscope parameters of defocus and astigmatism. The ultimate goal of such tasks is to fully adjust the operating parameters of the microscope and obtain an optimum image for viewing in terms of its information content. The initial approach to this problem, for high resolution TEM imaging, was to obtain the power spectrum from the Fourier transform of an image, find the contrast transfer function oscillation maxima, and subsequently correct the image. This technique requires a fast computer, a direct memory access device and even an array processor to accomplish these tasks on limited size arrays in a few seconds per image. It is not clear that the power spectrum could be used for more than defocus correction since the correction of astigmatism is a formidable problem of pattern recognition.

<div><p><em>The article presents the dynamics of the main factors for the development of modern television, the transition from traditional technologies of television broadcasting to the latest technologies. The process of developing digital television and broadband has been technically determined to address the challenge of integrating new technologies into traditional TV content. Ways of expanding the possibilities of interaction between the viewer and the television producer in the context of overcoming the crisis of traditional technologies are analyzed. It is determined that integration, development of mobile communications and Internet technologies are a hallmark of the modern world media space and have a significant influence on the formation of public opinion. The analysis of actual media researches concerning problems of the theory of mass communication is carried out. The phenomenon of «social television», which combines watching TV with simultaneous communication in social networks, is considered. The author draws attention to the disclosure of the determining factors of media communication, the study of the process of feedback from viewers on television. It is stated that the development of modern technologies, namely digital broadcasting and introduction of broadband Internet access to create a multimedia platform that combines Internet communication services and television content, contributes to improving the mechanism of interaction between the TV and the viewer. The theory of the conceptualization of journalism based on identity construction is examined: journalists understand their audience and, as members of that audience, connect with their communities. An analysis of integrated journalistic activity is conducted, which consists of three stages: gathering, editing and disseminating information. It is determined that the influence of the Internet allows the consumer to play his or her role at each stage, thus helping the journalist determine the degree of relevance of the story to himself and to the potential audience. The common features of modern telecontent were singled out and a comparative analysis of the trend of development of interactive TV programs of the USA, UK and Ukraine was made.</em></p></div><p><strong><em>Key words:</em></strong><em> public opinion, two-vector communication, feedback, communication methods, television audience, country telephony.</em></p>

It is argued that the digital technology has made possible the vast range of applications and media forms including virtual reality, digital special effects, digital film, digital television, electronic music, computer games, multimedia, the Internet, the World Wide Web, digital telephony and so on [8]. Digital transformation has been particularly influential in new directions of society.Providing schools with digital technology promises a high return on investment. The presence of computers and Internet access raises technology literacy and skills, better preparing the future generations to participate in the information society [12]. To this end, schools represent ideal access points because they cover a large part of the population, especially in developing countries. Starting from 1990s, many educators have been realised the potential of Internet for educational purposes and began to introduce it into classrooms. According to [10] the popularity of web-based teaching and learning lies in the strengths of its distributed nature and the case of its browsing facility. Both the use of digital technology and increased interest in student-centered learning may lead to a significant change of the teacher’s role, as well as the recognition of the active role of the learner in the learning process.
