ABSTRACT:
A hydrophone-filter with the frequency response characteristics of a geophone utilizes a second order high pass filter wherein one capacitive element of the filter is the hydrophone itself. The filter includes an amplifier, wherein one input receives a biasing voltage from a resistive network, and the other input receives a signal provided by one or more hydrophones. The filter also includes one or more capacitive elements and one or more resistive elements. The natural frequency and slope of the filter depend upon the values of the capacitive elements of the circuit, including the capacitance of the hydrophones, as well as the values of the resistive elements of the circuit. Advantageously, the natural frequency of the hydrophone-filter remains constant even if the magnitude of the hydrophone's output changes.
