Which consequence occurs when a Wien bridge oscillator's transfer function reaches a pole on the imaginary axis?

💡 Explanation

When the transfer function has poles on the imaginary axis, marginally stable oscillation at specific frequency occurs because feedback loop gain equals 1, causing sustained sinusoidal signal generation. Therefore, a stable oscillation occurs rather than damped oscillation, distortion, or unstable runaway implying poles that are negative or have positive real components.
