In the digital display set of the scale driving inductosyn, the demand for the symmetry for the double- road preamplifier is very strict.In the paper, the measuring errors of the displacement caused by the phase deviation and the amplitude deviation in the double-road symmetrical amplifier is analysed. It leads to a relationship which must bes atisfying for avoiding one digital error caused by the phase deviation and the amplitude deviation;A RC phase shift network which can be continually adjusted in both positive and negative directions is introduced, so as to satisfy the index demand put by the above relationship for double -road symmetrical amolifier. The conditions of the optimum design of the phase shift network arc emphasised. It has been proved by the experiment that the RC phase shift network based on the conditions of the optimum design gives higher precision, less attenuation. The phase can be continually and uniformly adjusted in both positive and negative directions and the amplitude of the transmisslo function of the phase shift network has only a little variation with the phase adjustment.The double- road symmetrical amplifier with an introduced RC phase shift network is recommended in this paper.The predetermined targets have been completely achieved through the experiment.

在定尺励磁感应同步器数显装置中,对两路前置放大器的对称性要求是很严格的。 本文对两路对称放大器中,由于相位偏移和幅值偏差所产生的位移测量误差进行了分析,并导出了为避免由于相位偏移和幅值偏差所产生的一个字误差必须满足的关系式:Δφθ<2(θ_机-θ_电) Δθ<δ/2θ_机sin2θ_电 为了满足上述关系式对两络对称放大器提出的指标要求,引入了相位能在正负方向连续可调的RC移相网络。文中着重阐明了该移相网络的最佳设计。通过实验,证明了按最佳设计条件设计的RC移相网络具有精度高、衰减小、相位能在正负方向连续均匀可调和移相网络传输函数幅值随相位调节变化很小等优点。 文中介绍了一个引入PC移相网络的两路对称放大器电路,实验结果完全达到了预定的指标要求。
