2.1.8 Bandwidth and Gain Flatness
Closed-loop current sensors have two signal paths which enable them to measure both DC and AC
current signals. At DC and low frequencies (that is, less than 100 Hz), the active loop with the fluxgate
dominates. At higher frequencies, the sensor acts like a current transformer.
