The feedback resistors set the gain to sustain oscillations. The circuit operates around 159 Hz, producing a stable low-frequency sine wave. #sinewavegenerator #ElectronicsEducation #electronicsrd | Electronics Education | Facebook

This simulation represents a Wien bridge oscillator, a widely used op-amp based sinusoidal oscillator known for its low distortion and stable output. The circuit uses a Wien bridge RC network consisting of a series RC and a parallel RC combination. This network provides frequency-selective positive feedback and produces zero phase shift at the oscillation frequency. At this frequency, the bridge is balanced and the feedback magnitude is exactly one-third. The op-amp is configured as a non-invert
