ABSTRACT:
A multiplexing node is associated with each analog sensor of a line array. ach multiplexing node has an amplifier/filter section coupled to its associated analog sensor for amplifying and shaping a signal generated by the sensor. An A/D converter then samples the signal. A receiver is coupled to a previous one of the multiplexing nodes for receiving scrambled data and clock information in serial fashion from the previous node. A descrambler is coupled to the receiver to separate the data from the clock. A processor is coupled to the A/D converter and the descrambler. The processor time division multiplexes the data and clock from the previous node with the sampled signal from the A/D converter. The processor scrambles the so multiplexed data, clock and sampled signal. A transmitter is coupled to the processor to transmit the scrambled data, clock and sampled signal in serial fashion over a single data line.
