This simulation shows a sine wave generator built using a Wien-bridge oscillator configuration. The two 1 kΩ resistors and two 1 µF capacitors form the Wien-bridge network, which determines the oscillation frequency—around 159 Hz, matching the oscilloscope reading. The op-amp provides the necessary gain to sustain oscillations, while the 48 Ω and 100 Ω resistors control loop stability and amplitude. As the circuit starts, noise is amplified and shaped into a stable sinusoidal waveform. The oscil
