+* Data-acquisition electronics measures the currents in the three transmitter coils, and measures the voltages induced in the three receiver coils.
* Receiver coil signals can be measured simultaneously or sequentially. Simultaneous measurements improve signal-to-noise ratio.

Line 74:
* Some designs use DC pulses to drive the transmitter coils, instead of AC frequencies. This simplifies driver design, but makes receiver signal recovery more difficult. DC pulse-driven transmitter coils must be driven sequentially.
