干涉式光纤陀螺的电子线路中不可避免会产生延迟，使得输出增加噪声并影响陀螺精度。为了解决上述问题，讨论了光纤陀螺数字电路的延迟对输出的非线性影响，并提出了相应的改善其影响的设计方法。另外对于为了减小数模转换器非线性噪声而增加的输出滤波器，也进行了设计，并同时指出了改变平均算法形式或使用平均算法以外的滤波器时应注意的事项。通过精心设计，可以达到彻底消除延迟影响的目的。仿真结果表明由于延迟引起的输出噪声标准差可以限制到零。

The delay of the digital circuit of an IFOG is inevitable, which will result in the noises in the output data and reduce the accuracy of the IFOG. In order to solve the problem, the effects of the delay of the digital circuits to the nonlinearity of the output of the IFOG are discussed, and the method of improvement in designing the digital circuits is recommended. The design of the output filters for reducing the noise from nonlinearity of D/A is put forward, and some of the attentions are also pointed out when changing the type of the average or using the filters other than an average. The purpose of elimination of the effect of the delay is obtained with the proposed design. The simulation shows that the SD of the noise in the output data due to the delay can be limited to zero.
