| Abstract: | In the system developed in this paper, a moving-coil infrasound sensor is fabricated on a piece of PET （Polyethylene Terephthalate）film. The output signals of the sensor are processed through a amplifier and a filter , and finally transferred to a LCD displayer controlled by a Magal6 single-chip microcomputer. Both of the frequency and intensity can be displayed at the same time. The system not only meets the measurement requirements, but also has high cost performance and portability. |
