One of the important requirements on oscillators is to have stable frequency of oscillation. The frequency stability problem for vacuum tube oscillators has been extensively in-estigated, however, the same problem for transistor oscillators has not been adequately treated. It is therefore the purpose of this paper to offer a detailed analysis on the frequency stability of transistor feedback oscillators.General equation of oscillations for feedback oscillators are first derived by using the linear analysis based on the cascade parameter matrix representation of 2-port networks. Analysis is then applied to the various types of transistor feedback oscillators. Various types of the equivalent circuits for the common-emitter network and various forms of feedback networks using only pure reactive elements are used in deriving the equationsof oscillations. Elements of the feedback networks are assumed to remain unchanged andparameters of the transistor networks are assumed to be varied in the investigation of the frequency drift of transistor oscillators.Feedback networks are grouped into three major groups according to their geometries: the three-arm π configurations, the four-arm and the five-arm configurations. Conditions of oscillations, conditions of frequency stability for oscillators using these groups of feedback networks are discussed and results are summarised into three tables for ready references.

振荡器的一项重要性能是振荡频率的稳定度,对电子管振荡器的频率稳定性能已有比较长时期的研究。然而,对晶体管振荡器频率稳定性能的研究则尚欠完善。本文将对晶体管反馈振荡器的频率稳定性能作比较详细的研讨。 根据四端网络分析及级联参数矩阵表示法,首先推导反馈振荡器的通用振荡方程,然后对共发射极网络的各种等效电路以及对各种纯电抗元件的反馈网络的级联参数进行分析,用这些网络形成各种晶体管反馈振荡器,并推导这些振荡器的振荡方程。根据振荡方程对这些振荡器的振荡性能,包括振荡频率的稳定性能,进行分析及比较。 假设反馈网络所用外加电抗元件固定不变,而晶体管参数改变(包括晶体管的输出输入电阻,输出输入电容,电流放大系数的虚数部分,负载电阻等的改变),对由于这些参数改变所引起的振荡频率漂移作了分析及比较。 根据所用反馈网络的几何构造,将反馈网络分成三臂π形,四臂及五臂网络等三类,对采用这三类网络而组成的晶体管振荡器的振荡性能进行分析,重要结果分别在三表中列出,供研究及设计者参考。

文中提出了一种由同步马达拖动的电-机械式超低频函数发生器。它的输出几乎没有漂移,在整个工作频带内,不会引起输出幅度的改变,振幅十分稳定。用不稳定度不超过0.1%的恒流电源供电,其他技术指标,如正弦波的非线性失真、频率稳定性和频率误差等,都不逊色于电子式超低频函数发生器。它的输出可供对函数信号有特殊要求的场合使用。本文对这一函数发生器的工作原理作了详细的叙述,其中着重讨论了正弦-余弦函数变换器、电源的选择、电源与函数电位器的最佳连接方案以及恒流电源的工作原理,还阐述了如何有效地消除由电源变压器所引入的干扰信号。
