| 摘 要： | 本文提出并论述了一种新的有源电阻正弦波振荡器。这种振荡器仅由两个集成运放和电阻组成。理论分析和实验结果表明:只需调节一个接地的电阻,振荡频率可调范围相当宽;两个运放输出的正弦波是正交的。这种振荡器在数字通信和测量仪器中很有用。它可用作为波形、频谱分析仪的本机振荡器,也可用作为数字调制的移频键控(FSK)、移相键控(PSK)信号发生器。

| Abstract: | ——In this paper,a new active—R sinewave oscillator consisting of two operatinal ampli- fiefs(OAs)and resistors is proposed.Analyzing and experimental results show that a fairly wide range of oscillation frequency can be controlled by a single grounded resistor.Sinusoids of the two —OA outputs are orthogonal.The proposed oscillator is useful for digital communication and instru mentation.It can be used as the local oscillator in wave/spectrum analyser.It also can be used as a new digitally modulated FSK/PSK signal generator. |
