A Signal Processing Circuit for Shock Wave Pressure Sensor


Article Preview

A cheap signal processing circuit was designed to replace expensive special charge amplifier which was used for shock wave pressure sensor. We used conventional electrical components to design the charge amplifying circuit and the filter circuit. A fine image of shock pressure wave was got using this signal processing circuit in a real fire experiment.
