  • Easy to build pulse induction metal detector with DSP

    Introduction to Metal DetectionSearch Coil DesignThe Discharge Curve and DiscriminationPower Supply DesignMost metal detectors work on the fact that metals in a magnetic field change the behavior of the field. There are two general approaches to detect these changes. In one approach, an alternating current is provided to a transmit coil. A receive coil is used to pick up the magnetic field generated by the transmitter. If a piece of metal comes inside the range of the magnetic field lines, the receive coil can detect a change in both amplitude and phase of the received signal. The amount of amplitude change a
