  • Underwater acoustic transmission method and equipment to improve the intelligibility of such transmissions
    Patent number: 5572485
    Abstract: A method for underwater, acoustic transmission, characterized in that at the transmitting side, the signal to be transmitted first is sampled, digitized and stored and then un-sampled and un-digitized at a frequency less than the sampling frequency and is thus transmitted in analogue form, and in that at the receiving side the signal is correspondingly sampled, digitized and stored at the said un-sampling and un-digitizing frequency and then is re-read at the said sampling frequency.
