## ABSTRA CT The low frequency (below 150 Hz) acoustic ground impedance was determined on a large uncultivated field using an impedance meter, the probe microphone method, a modified Biot-Stoll type calculation, and the phase gradient method. The impedance measured with the impedance meter has low

The effects of electrochemical systems non-linearities on impedance measurements with a Frequency Response Analyser have been investigated in low frequency domain from both a theoretical and experimental viewpoint. A theoretical expression for the polarization resistance measurement error has been f
The system consists of an enclosed waveguide operating in the fundamental mode, with an array of microphones and data processing electronics for determining the complex reflection coefficient of a surface two meters square.
An on-line real-time system utilizing a simple package of dedicated hardware in conjunction with a small computer for measuring two-terminal electrical impedance is described. Operating efficiently from0.005 to 500 Hz, it covers most of the interesting range for bioelectrode, organ, and tissue studi
The article is devoted to curve fitting of the measured frequency response functions (FRFs) of an actual beam with a non-linear component. A frequency response model, based on the non-linear normal modes (NNMs) approximated by the Ritz-Galerkin method and on a superposition assumption is built up. I
Two-point low frequency impedance measurements of microstrip transmission lines, fabricated from thick YBCO ( + 10 wt.% Ag) films on YSZ and sapphire substrates, have provided intrinsic properties for these granular thick films. The variation of the resistance with temperature for all the films stud
