Metal Detector using a 2 Pulse Induction Coil

2006-10-24  pulse induction metal detector is a device with use in many different fields such as recreation, security or medicine. PSPICE was used to simulate the circuit and the coil used for metal detection was successfully modeled by using different values for inductors. The different waveforms obtained from the simulations can be observed in Appendix B.
