This book was released on 1966 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: A great deal of study has been given to the demodulation of FM and PM modulated signals. This report is the first of a two-volume series which reviews and contributes to the body of information on this subject. In this volume, three new techniques are discussed which are useful for the demodulation of angle-modulated signals. The three techniques analyzed are: (1) nonlinear post-detection filtering, (2) subharmonic phase-locked loop, and (3) feedforward deviation compression demodulator. The performance of these techniques is analyzed both with respect to noise effects and distortion. Emphasis is given to telemetry signal processing. Several computer (digital) programs were generated to carry out these investigations and nonlinear post-detection filters were simulated on an analog computer. In addition to the three new techniques studied in this report, several other topics are treated. One important topic is a precise analysis of the distortion in phase-locked loops. The second is a review of the effects of predetection recording on telemetry signals. (Author).

Download or read book Demodulation of Angle modulated Telemetry Signals Volume Ii Review of Demodulation Methods written by J. J Spilker (Jr) and published by . This book was released on 1966 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents a review of the various methods available for the demodulation of the angle-modulated sinusoids. Three major sections are contained in this report: Demodulation of Analog Angle-Modulated Signals (Conventional FM Discriminators) (Phase-Locked Demodulation), Special Feedback and Feedforward Demodulators for Analog Modulated Signals, and Digital Signalling. In Section 2 conventional discriminator detection is discussed along with various forms of phase-locked demodulation. These areas have received the greatest attention in the literature and consequently are given the greatestspace in this report. Section 3 describes a wide variety of special feedback and feedforward demodulation methods for angle-modulated signals. The frequency-feedback demodulator is considered here along with the numerous forms of 'modified' phase-locked loops. Feedforward demodulation methods are also discussed. Nonlinear post-detection filtering, described in greater detail in Vol. I (AD-639 787), is reviewed here for completeness. Various binary and M-ary methods of digital signalling are reviewed in Section 4. Optimum and near-optimum detection methods are described for: PCM-FM, FSK, PSK, DPSK, MPSK, M-ary coded PSK, and MFSK. (Author).

Download or read book Converging Technologies for Improving Human Performance written by Mihail C. Roco and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: M. C. Roco and W.S. Bainbridge In the early decades of the 21st century, concentrated efforts can unify science based on the unity of nature, thereby advancing the combination of nanotechnology, biotechnology, information technology, and new technologies based in cognitive science. With proper attention to ethical issues and societal needs, converging in human abilities, societal technologies could achieve a tremendous improvement outcomes, the nation's productivity, and the quality of life. This is a broad, cross cutting, emerging and timely opportunity of interest to individuals, society and humanity in the long term. The phrase "convergent technologies" refers to the synergistic combination of four major "NBIC" (nano-bio-info-cogno) provinces of science and technology, each of which is currently progressing at a rapid rate: (a) nanoscience and nanotechnology; (b) biotechnology and biomedicine, including genetic engineering; (c) information technology, including advanced computing and communications; (d) cognitive science, including cognitive neuroscience. Timely and Broad Opportunity. Convergence of diverse technologies is based on material unity at the nanoscale and on technology integration from that scale.
