    Amplitude demodulation of variable frequency digital signals
    (National Aviation University, 2023-06-22) Gorshkova, Kateryna; Горшкова, Катерина Андріївна
    Undoubtedly, we present an introductory discourse for a diploma thesis concerning the amplitude demodulation of variable frequency digital signals. The present study aims to provide a comprehensive analysis of the topic at hand. This introductory section serves to offer a glimpse into the study's overall objective and intended approach, in an effort to articulate the relevance and importance of the topic to the reader. By contextualizing the subject matter within existing scholarly literature and established theoretical frameworks, this study seeks to contribute new insights and perspectives to the discourse. In contemporary times, in light of advanced communication systems and the emergence of digital signal processing, precise demodulation of variable frequency digital signals is of utmost significance. Amplitude modulation (AM) is a modulation technique that is extensively employed for the transmission of information through a carrier signal. The process entails modulation of the amplitude of the carrier signal in accordance with the underlying digital data intended for transmission. Nonetheless, the demodulation of signals featuring varying carrier frequencies presents noteworthy complexities that arise from the dynamic nature of the carrier frequency. The process of demodulation is a vital aspect in the retrieval of the original digital information from the modulated signal. The process of amplitude demodulation involves the extraction of amplitude variations imposed by the modulation process, with the specific aim of recovering the underlying digital signal. The signal that has been demodulated is a true and accurate indication of the initial digital information, thereby facilitating subsequent examination, interpretation, and application. The objective of this thesis is to explore and advance methods pertaining to the process of amplitude demodulation of digital signals that exhibit variable frequency characteristics. The primary aim is to develop algorithmic solutions that are efficient and dependable in accurately demodulating signals characterized by fluctuating carrier frequencies, notwithstanding the presence of noise, interference, and other transmission obstacles.
