Abstract :
Approximate equations are derived that allow calculation of the component values for a multiple-mode Mason equivalent circuit for acoustic transducers. The experimental approach required to obtain the data from which to derive the equivalent circuit is also described. The equations have been tested for accuracy, and the approach described here yields useful information for the system designer. Iterative procedures can be applied to further refine the calculated values.<>
