ABSTRACT:
Compensation for interaction between separate channels of a noise cancellation system in a vibrating or noisy structure is obtained by the addition of pre- and post-processing circuits for channel controllers to electronically separate the channels so that each channel operates on uncoupled modes of vibration. The processing circuits include sum and difference elements.
