逆重复伪随机序列信号相关分析法在探测蝇复眼电反应中的应用

伪白噪声测试信号的相关分析法,对于黑箱辨识问题来说,是较为合适的实验手段。隨着这种方法应用的扩展,特别是应用于生理系统,提出了如何进一步选择合适的输入信号的问题。逆重复伪随机二进制序列是较为合适的。本文介绍了逆重复伪随机序列信号相关分析法在探测光引起的蝇复眼反应中的应用,描述了信号的产生,测量并计算了模拟输出,它和实测结果甚为符合,说明这种方法对预测反应具有较高的精确性

USE OF INVERSE REPEAT SEQUENCE TEST SIGNALS AND METHOD OF CORRELATION IN THE PREDICTION OF ELECTRICAL RESPONSES OF THE COMPOUND EYES OF HOUSEFLY

Crosscorrelation method of system identification using quasiwhite test signalsis one of the most powerful approaches to the black-box identification problem.The increasing use of the method in system identification,particularly in physio-logical systems,has raised the question of selection of appropriate quasiwhite testsignal.The inverse-repeat-sequence poses as a principal canditate in this selec-tion.It is one type of the pseudo random binary signals based on m-sequences.This paper demonstrates that crosscorrelation method using inverse-repeatsequence test signals can be used to predict the photic response of the compoundeyes of housefly with fair accuracy.
