Acoustic Vector-Corrected Impedance Meter [PDF]
, 2014 We describe the development of a novel instrument intended for the measurement of the acoustical reflection coefficient of materials. The instrument effectively implements a one-port vector-corrected network analyzer in the acoustic, rather than the ...

Coronary input impedance during cardiac cycle as determined by impulse response method
, 1987 The coronary arterial system was characterized by its input impedance determined in systole and diastole from impulse response functions in five dogs. The impulse response technique was verified on a known hydraulic system.

Impulsive impedances in lossless circuits: Fourierand Laplace methods
Electronics Letters, 2000 A proposal for adding impulsive components of impedance/admittance to the reactance/susceptance for lossless transmission lines is extended to all lossless resonant circuits. This new Fourier analysis yields a finite rate of energy transfer from a lossless source while the orthodox analysis would give an unbounded steady-state energy transfer.
