Abnormal oscillation

A phenomenon in electrical and electronic circuits where unexpected oscillation occurs at a certain frequency due to design or wiring defects, leading to functional issues. In amplifier circuits, this can happen when part of the output feeds back into the input, causing repeated amplification. Accurate design and wiring are important to prevent abnormal oscillations. As a countermeasure when oscillation does occur, changing the CL value of the component is one method. Also known as modulation disturbance.
