摘要
在通信、检测电路中,作为调制和解调载波信号发生器的振荡电路,其频率稳定度是振荡器的一个很重要的指标.在阐明了频率稳定度的基础上,分析了三点式振荡电路中影响频率稳定性的各种因素,最后给出了一种改进型高稳定度的振荡电路.
In the field of communication and detection, the stability of output for oscillator circuits as the carrier wave generator, is an important figure. This paper analyses the factors that affect the stability of frequency in three\|point oscillator circuit based on declaring the definition of frequency stability. Finally, an improved oscillator circuit with high stability of frequency is introduced in the paper.
