Abstract : The patent relates to a fixed electrical network, in conjunction with an amplifier having variable output impedance, used to provide each of the transducer elements of an array with a reactance which acts as a large shunt reactance when the amplifier acts as a constant current source, but which acts as a smaller series reactance when the amplifier acts as a constant voltage source. Consequently, the usable bandwidth of the array is greatly increased, without degrading its performance.
