Abstract
Systems and methods of identifying electrical sources of audible acoustic noise may involve identifying first frequency content of a circuit board, wherein the first frequency content is associated with at least one of acoustic noise and a vibration of the circuit board. Second frequency content of an electrical signal associated with the circuit board may also be identified. In addition, a coherence between the first frequency content and the second frequency content may be determined.
