本文提出了一种设计三值扰动信号的方法，以减小线性系统辨识中非线性失真和噪声的影响。这是通过抑制信号中2和3的谐波倍数并优化三个性能指标来实现的。给出了设计原始三进制信号，以满足这些标准的方法，并列出了结果的信号周期高达78。然后表明，这些信号可以用来设计伪随机三进制信号，也符合标准的较长的周期。这些信号的结果制成表格，并举例说明。
Abstract A method is described for designing ternary perturbation signals to reduce the effects of both nonlinear distortion and noise in the identification of linear systems. This is achieved by suppressing harmonic multiples of 2 and 3 in the signals and optimizing three performance indices. Methods are given for designing primitive ternary signals to meet these criteria, and results are tabulated for signals with periods up to 78. It is then shown that these signals can be used to design pseudorandom ternary signals with longer periods that also meet the criteria. Results are tabulated for these signals and illustrated by an example.
