R-C正弦波振荡器是以电阻、电容为选频元件和以电子管、晶体管或集成电路为放大元件所组成的。它和LC型振荡器相比较,其特点是振荡频率的覆盖可达很宽、元件体积小、价格经济、调节方便,能制成高质量的音频信号发生器。它能提供非线性失真很小,频率、幅度稳定度较好的宽带正弦波信号。因此在无线电工程、无线电测量、电磁测量以及自动化技术、振动测试、地震地质测试、医用电子设备、模拟系统等非电量的研究、测试中是应用十分广泛的仪器。
R-C sine wave oscillator is a resistor, capacitor for the frequency-selective components and tubes, transistors or integrated circuits for the amplification components. It is compared with the LC type oscillator, which is characterized by a wide range of oscillation frequency coverage, small components, affordable, easy to adjust, can be made of high quality audio signal generator. It can provide a small nonlinear distortion, frequency, amplitude and stability of a good wide-band sine wave signal. So in radio engineering, radio measurement, electromagnetic measurement and automation technology, vibration testing, seismic geology testing, medical electronic equipment, analog systems and other non-power research and testing is the application of a wide range of instruments.
