This paper presents a simple method by which the phase angle between the fundamental components of two non-sinusoidal waves can be measured. Applications of this method in an electron tube amplifier and oscillator arc discussed.

设有两个非正弦波,其基本频率相等,将此二波变为两电压,接至阴极射线示波器之两对偏转板极,则产生一复杂之李氏图形。此图形之总面积,与二波中基本频率之相角,有一极简单之关系。本文指出此种关系之存在,并引用於电子管放大器及振荡器中相角之测量。

The results presented in this paper may be classified into three categories. First, there is derived the characteristics of gain, bandwidth, and figure of merit of a non-degenerative parametric amplifier of both fundamental and sub-harmonic pumping; and the comparison between them is carried out in substantial detail. Second, there is devised an analytical method for determining the harmonic contents of the capacitance of a nonlinear semiconductor diode, which is negatively biased and is under the action of a strong high frequency pumping voltage. The magnitudes of bias and pumping voltage are thus found quantitatively. Also, the stability requirements for pumping amplitude and pumping frequency are discussed. Third, the noise figure of a parametric amplifier itself and the effective noise figure of the amplifier loaded with a noisy second stage, which may be a frequency converter, are derived. Factors such as diode loss, match, and the bandwidth ratio of the signal to the idler circuit are all considered in the derivations so as to make the results with greater importance for practical applications. Finally, a numerical example is given to show the utility of the results presented in this paper and to illustrate a possible design procedure of a non-degenerative parametric amplifier.

本文主要结果有三:第一,推导出基波激励和次谐波激励参量放大器的优值、功率增益、和通带等主要特性,并就这些特性对基波激励源的和次谐波激励源的参量放大器进行比较;第二,通过半导体二极管非线性电容的谐波分量的分析,在激励电压、偏压和放大器的特性间得出定量关系,并且对给定放大器特性求出激励源幅度和频率的稳定要求;第三,推导出放大器的有效噪声,并给出最低有效噪声的设计条件。 以上特性的探讨和二极管损耗、信号迴路和镜象迴路通带比、匹配等因子结合在一起进行,使所得结果更具有实际意义。最后举出一数字例子,说明应用本文结果来设计参量放大器的一种可能步骤。

It is found by the measurement of charaeteristie of electrometer tubes that the com-pansation effect to zero drift and fluctuation of amplifiers with bridge type, such as Du-Bridge's and Barth's circuit, are characterized by the tube itself. The points of compa-nsation characteristic may be deseripted by a set of equaltions. The design calculation from the equaltions fit with experiments. At the same time a semi-experimental method for circuit design, and a calculation method for the gain of amplifiers...

It is found by the measurement of charaeteristie of electrometer tubes that the com-pansation effect to zero drift and fluctuation of amplifiers with bridge type, such as Du-Bridge's and Barth's circuit, are characterized by the tube itself. The points of compa-nsation characteristic may be deseripted by a set of equaltions. The design calculation from the equaltions fit with experiments. At the same time a semi-experimental method for circuit design, and a calculation method for the gain of amplifiers are driven,A conception of half-saturation of space charges effect, is given for explanation about the new phenomena met here.

根据静电计电子管特性的测量结果,静电计管桥式直流放大器,例如杜伯利智及巴特电路,对于零点漂移与起伏的补偿作用,是由电子管本身的特性来决定的。电子管的补偿特性可以用一组方程式来描写。由方程组的设计计算与实验符合。同时,并根据电子管的特性,导出一个半实验性的放大器电路设计方法,及放大器增益的计算方法。 对遇到的新现象,作者用称为空间电荷效应半饱和的概念来解析。
