Underwater Signal Conversion
First Claim
1. A system, comprising:
- a first conversion component configured to convert a high frequency alternating current signal to a direct current signal, where a voltage value of the direct current signal corresponds to a frequency value of the high frequency alternating current signal;
a second conversion component configured to convert the direct current signal to a low frequency alternating current signal, where the frequency value of the low frequency alternating current signal corresponds to the voltage value of the direct current signal; and
a transmitter configured to, when underwater, transmit the low frequency alternating current signal to a near-field receiver that is also underwater.

Abstract
Various embodiments associated with signal conversion while underwater are described. A source can transmit an alternating current signal with a relatively high frequency over a relatively long distance. The alternating current signal with the relatively high frequency can be converted to an alternating current signal with a relatively low frequency. An example of this conversion can be done by converting the alternating current signal with the relatively high frequency into a direct current signal. The direct current signal can then be converted into the alternating current signal with the relatively low frequency. The alternating current signal with the relatively low frequency can be transmitted from a transmission coil to a pick-up coil. After reception by the pick-up coil the alternating current signal with the relatively low frequency can be processed, such as processed to determine a direction of the source of the alternating current signal with the relatively high frequency.
