通过对光电靶原理的分析,证明了弹丸所引起的光电靶输出信号与声波、蚊虫等所引起的光电靶输出信号是不同的。在此基础上,提出了一种利用CPLD(complexprogrammablelogicdevice)器件实现抗干扰电路的方法。仿真分析和应用结果表明:该电路能有效地抑制声波和蚊虫等带来的干扰,明显地提高了电路的抗干扰能力,保证了测试结果的可靠性和精确性。
Through the analysis of the principle of photoelectric target, it proves that the photoelectric target output signal caused by projectile is different from that of photoelectric target caused by sonic wave, mosquito and so on. On this basis, a method of realizing anti-interference circuit using CPLD (complex programmable logic device) is proposed. The results of simulation analysis and application show that the circuit can effectively suppress the interference caused by acoustic wave and mosquito, improve the anti-jamming capability of the circuit obviously and ensure the reliability and accuracy of the test result.
