A real-time, or synchronous, sensor data acquisition system (10) acquires physical characteristics or properties associated with a structure (14) or physical system using a plurality of sensors (18) coupled in series to a single cable (26). The sensors (18) may sense vibration, noise, temperature, acceleration, pressure, strain, force, etc. The sensors (18) transmit data along the cable (26) at greater than 100dB dynamic range, with a bandwidth between about 5 to 20 KHz, and in a digital, single bit wide data stream. The sensors (18) include modulators to code the data signals with distinct codes. A receiver has a demodulator to decode and separate the data signals.
