A multi-frequency quadrature bridge

1998 Conference on Precision Electromagnetic Measurements Digest (Cat. No.98CH36254), 2002
A quadrature bridge has been developed with the aim of determining capacitance values at several frequencies in terms of a resistance ultimately derived from the QHR. The bridge is evaluated by comparing a 1 nF capacitor with a 100 k/spl Omega/ resistor at six frequencies from 3/8/spl times/10/2/spl pi/ kHz to 10/2/spl pi/ kHz.

An UWB Multi-frequency transformer

2006 10th IEEE Singapore International Conference on Communication Systems, 2006
A novel multi-frequency transformer is developed based on dual frequency transformer reported recently. Different from dual frequency transformer, which has two steep poles, the return loss curve of the transformer developed in this paper has one steep pole with two gentle side poles.

Multi-frequency transmission tomography

The Journal of the Acoustical Society of America, 1983
Multi-frequency signals were transmitted using a plane-wave transducer, through a water immersed phantom consisting of two finger cots, one containing 50% isopropanol alcohol and the other containing normal saline. The scattered ultrasound was received with a small hydrophone and detected with a quadrature detection system.
