Irregular rhythm

Used synonymously with abnormal emission. In electrical and electronic circuits, this phenomenon occurs when, due to poor design or wiring defects, unintended oscillation arises at a specific frequency and disrupts functionality. In amplifier circuits, it may occur when a portion of the output feeds back into the input and amplification is repeated. To prevent abnormal oscillation, accurate design and wiring are important. If it does occur, one countermeasure is to change the CL value of the component.
As a distinct usage separate from abnormal emission, this term can also refer to a phenomenon during parallel operation of generators in which the rotor oscillates back and forth around the synchronous speed due to sudden changes in load or driving torque. If the hunting of the generator becomes severe, it may deviate significantly from synchronous speed and lose synchronism, resulting in shutdown.
