Abstract : A hydrophone analog signal data acquisition, A/D conversion and data transmission system includes a first-stage signal processing subsystem which provides digital representations of the hydrophone analog signal, which in turn are signal processed for transmission in the form of data packets by a second stage signal processing subsystem. Subsystem 40 includes a plurality of Data Multiplexer/FIFO units, including corresponding selectively acting data unit accumulators, each accumulator having a plurality of inputs coupled to output channels of the first-stage signal processing subsystem for receiving digital representations of hydrophone analog signals. Each data unit accumulator includes a first buffer for storing information that includes a digital representation of the analog hydrophone signal, an identification of a hydrophone that generated the acoustic information, and a time that the acoustic information is received from the hydrophone.
