Book Surface Wave Devices for Signal Processing

Download or read book Surface Wave Devices for Signal Processing written by D.P. Morgan and published by North Holland. This book was released on 1985 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen the emergence of a wide variety of electronic devices making use of surface acoustic waves in solids. This book focusses on the devices of greatest current interest and on the principles underlying them. An introductory survey is followed by chapters on acoustic wave fundamentals, electric excitation, transducers, multi-strip couplers and propagation effects. The interdigital transducer is emphasised since it is a key element in most devices. The remaining chapters - about half of the book - describe practical devices including delay lines, bandpass filters, chirp filters for pulse-compression radar (including reflective array compressors), convolvers and oscillators. For the main devices the text includes design principles, second-order effects, practical performance and, where appropriate, the role of the device in system applications. Some of the more mathematical details are relegated to Appendices, which include electrode interactions in transducers, sampling theory, the electrostatic element factor and the required relationships from Fourier analysis. A classified list of over 500 references is provided.The book will be of interest to engineers developing surface-wave devices, and to those using the devices in practical systems. It is also very suited for university courses or research work.

Book Surface Acoustic Wave Devices and Their Signal Processing Applications

Download or read book Surface Acoustic Wave Devices and Their Signal Processing Applications written by Colin Campbell and published by Elsevier. This book was released on 2012-12-02 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface Acoustic Wave Devices and Their Signal Processing Applications is a textbook that combines experiment and theory in assessing the signal processing applications of surface acoustic wave (SAW) devices. The operating principles of SAW devices are described from a circuit design viewpoint. This book is comprised of 18 chapters and begins with a historical background on surface acoustic waves and a discussion on the merits of SAW devices as well as their applications. The next chapter introduces the reader to the basics of acoustic waves and piezoelectricity, together with the effect of acoustic bulk waves on the performance of SAW filters. The principles of linear phase SAW filter design and equivalent circuit models for a SAW filter are then described. The remaining chapters focus on trade-offs in linear phase SAW filter design; compensation for second-order effects; harmonic SAW delay lines for gigahertz frequencies; and coding techniques using linear SAW transducers. The final chapter highlights Some other significant alternative design techniques and applications for SAW devices. This monograph will be suitable for engineering or physics students as well as engineers, scientists, and technical staff in industry who seek further information on SAW-based circuits, systems, and applications.

Book Surface Acoustic Wave Filters

Download or read book Surface Acoustic Wave Filters written by David Morgan and published by Academic Press. This book was released on 2010-07-27 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface Acoustic Wave Filters gives the fundamental principles and device design techniques for surface acoustic wave filters. It covers the devices in widespread use today: bandpass and pulse compression filters, correlators and non-linear convolvers and resonators. The newest technologies for low bandpass filters are fully covered such as unidirectional transducers, resonators in impedance element filters, resonators in double-mode surface acoustic wave filters and transverse-coupled resonators using waveguides. The book covers the theory of acoustic wave physics, the piezoelectric effect, electrostatics at a surface, effective permittivity, piezoelectric SAW excitation and reception, and the SAW element factor. These are the main requirements for developing quasi-static theory, which gives a basis for the non-reflective transducers in transversal bandpass filters and interdigital pulse compression filters. It is also needed for the reflective transducers used in the newer devices. A thorough revision of a classic on surface acoustic wave filters first published in 1985 and still in print Uniquely combines easy-to-understand principles with practical design techniques for all the devices in widespread use today Complete coverage of all the latest devices which are key to mobile phones, TVs and radar systems Includes a new foreword by Sir Eric Albert Ash

Book Surface Acoustic Wave Transducer Study

Download or read book Surface Acoustic Wave Transducer Study written by B. J. Hunsinger and published by . This book was released on 1978 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical and experimental study of surface acoustic wave transducers is carried out to improve the modeling technique and the implementation configuration. The capacity weighted transducer with the response controlled by integrated circuit capacitors has been developed. The response is improved because the SAW beam has a uniform width and the transducer taps may be adjusted over a wide range. The excitation theory of transducers has been reformulated to account for nearest neighbor interactions over a wide range of harmonics. This modeling approach significantly expands the versatility and accuracy of the model. An experimental procedure for measuring the transducer excitation function is described. (Author).

Book Modeling and Measurement Methods for Acoustic Waves and for Acoustic Microdevices

Download or read book Modeling and Measurement Methods for Acoustic Waves and for Acoustic Microdevices written by Marco G. Beghi and published by BoD – Books on Demand. This book was released on 2013-08-28 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acoustics is a mature field which enjoys a never ending youth. New developments are induced by either the search for a better understanding, or by technological innovations. Micro-fabrication techniques introduced a whole new class of microdevices, which exploit acoustic waves for various tasks, and in particular for information processing and for sensing purposes. Performance improvements are achievable by better modelling tools, able to deal with more complex configurations, and by more refined techniques of fabrication and of integration in technological systems, like wireless communications. Several chapters of this book deal with modelling and fabrication techniques for microdevices, including unconventional phenomena and configurations. But this is far from exhausting the research lines in acoustics. Theoretical analyses and modelling techniques are presented, for phenomena ranging from the detection of cracks to the acoustics of the oceans. Measurement methods are also discussed, which probe by acoustic waves the properties of widely different systems.

Book Scattering Matrix Analysis of Surface Acoustic Wave Reflectors and Transducers

Download or read book Scattering Matrix Analysis of Surface Acoustic Wave Reflectors and Transducers written by Carl Michael Panasik and published by . This book was released on 1980 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phased periodic array scattering parameters have been modified and corrected for use as a single electrode, mixed units, scattering matrix consisting of one electrical and two acoustic ports. These scattering parameter analytical expressions are functions of material constants, electrode geometry, and frequency. The three port single electrode scattering matrices are acoustically cascaded to produce a three port device scattering matrix which takes into account all finger interactions (acoustic and electric) for the combined effects of piezoelectric and mechanical scattering. The analysis agrees well with experimental measurements of input admittance, electro-acoustic transfer function, and acoustic transmission and reflection coefficients as functions of frequency. Analysis results for the complete modeling of transducers with floating electrodes are also presented. (Author).
