Informationen zum Autor Stefan Bilbao received his BA in Physics at Harvard University ('92), then spent two years at the Institut de Recherche et Coordination Acoustique Musicale (IRCAM) in Paris as a student intern. He then completed the MSc and PhD degrees in Electrical Engineering at Stanford University ('96 and '01, respectively), while working at the Center for Computer Research in Music and Acoustics (CCRMA). His current research interests include the application of digital filtering and numerical simulation techniques to the physical modeling of musical instruments. Klappentext Reliable prediction through modelling forms the basis of engineering design. Circuit-based methods for the numerical integration of partial differential equations offer electronic and electrical engineers a simple and verifiable technique for defining efficient and stable models. The digital waveguide method, traditionally popular in the field of sound synthesis, becomes less reliable when applied to multidimensional systems and/or non-ideal media.* Provides a comprehensive overview of circuit-based numerical integration methods.* Presents a unified simulation method with potential applications in electromagnetics, acoustics, mechanics and digital signal processing.* The first book to cover these important simulation techniques in the English language.* Extends the application of traditional EE techniques to problems in civil and mechanical engineering bringing together four distinct research communities: wave digital filters, digital waveguide mesh, transmission line matrix, and general finite differences.The author investigates the relationship between this method and other techniques such as wave digital filters, and develops a unified general numerical simulation method that can be applied to a range of distributed systems in electromagnetics, acoustics and mechanics.
