| Abstract: | In the shockwave detection,the signals that the piezoeletrical sensors detect are weak,and the output are micro current.Common signal adjust circuit can not meet the requirements.Based on this problem,the research to the adjust circuit of the shockwave detection was carried out,the circuit including the charge amplifier,bandpass filter and output amplifier circuit.Bandpass filter bandwidth is between 3KHz and 8KHz and realized by higher precision AMP OP07.Charge amplifier circuit is realized by higher resis... |
