For understanding the physics of sound and the biophysics of acoustic sensors in animals, the concepts of impedance and admittance, impedance matching, transducer, transformer, passive and active, bidirectional coupling, and resonance are widely used. They all arise from the circuit-theory metamodel, which has been applied extensively in acoustics. As the name suggests, the circuit-theory metam...

Erratum: Equations D5 and E3 in the appendices of [1] contain typographical errors. They should read W ≡ diag(W í µí±›); W í µí±› ≡ í µí± � 0í µí±› í µí±£ 0í µí±› í µí±– 0í µí±› = í µí±£ 0í µí±› * í µí±£ 0í µí±› í µí± � 0í µí±› í µí± 0í µí±› * (D5) and U ≡ diag � |í µí±£ 0í µí±š | í µí±£ 0í µí±š �Re�í µí± ref í µí±š � �í µí± ref í µí±š � �.

Matrix Theory has long been applied to many branches of engineering. However, numerical difficulties have limited access to students, especially at the elementary level. This limitation has partially been removed with the development of canned software and modern scientific calculators which operate matrices. However, the approach with matrices ignores this and still follows traditional ways. T...

This paper reviews research activities in the area of topological aspects of circuit theory in Japan, most of which have been done after the previous report of H. Watanabe in the Special Centennial IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS, January 1984 issue, and presents main results obtained by Japanese circuit theorists. Throughout these research activities, it can be seen that the soul of ...

Analog circuits and and their interconnections, broadly called analog systems, are indispensable components of modern communication and electronic systems as well as electronic converters used in power systems. Almost all such circuits are built using active devices which require an external excitation for their operation. Active devices exhibit large sensitivity of performance to variations of...

Formulation of closed form expressions for computingMISR aliasing probability exactly had remained an unsolved problem.This paper presents single and multiple MISR aliasing probability expres-sions for arbitrary test lengths. A framework, based on algebraic codes,is developed for the analysis and synthesis of MISR-based test responsecompressors for BIST. This framework is us...
