As shown in figure, when it generates low-frequency sine wave, usually it uses the capacitor and resistor to determine the oscillation frequency of RC oscillator circuit. There are many RC oscillator network circuits such as the the Wien bridge oscillator circuit, T-shaped bridge oscillator circuit, phase-shifting oscillator circuit. Figure 6-13 is a Wien bridge oscillator circuit exa,ple, and it is composed of op amp A1 and some capacitors and resistors elements, etc. , and it can obtain the the stable sine wave with the degree of distortion being below 1%.
