Abstract
A valid analog signal regulated means is introduced for the weak signal produced by the magneto-resistive sensor.Weak magnetic signal acquisition system based on magnetroresistive sensor is designed.Weak signal is successfully detected and data is also acquired by this system and the feasibility and practicability of signal acquisition system are testified by experiment.
