Determining acoustical directionality in an impedance tube using multiple fixed microphones [PDF]
, 2011 Acoustic impedance of a port or object is a valuable piece of knowledge describing how well sound is transmitted or reflected. The commonly used slotted-line method is labourious and time consuming, requiring manual movement to find the maxima and minima

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.

Inference for Impulse Responses [PDF]
Poor identification of individual impulse response coefficients does not necessarily mean that an impulse response is imprecisely estimated. This paper introduces a three-pronged approach on how to communicate uncertainty of impulse response estimates ...
