Abstract
Statistical changes are manifested by the appearance of energy at certain known frequency triplets in the bispectral domain. This problem is motivated by the interest in monitoring machinery components for the purpose of detecting defects. Several spectral and bispectral detectors are discussed and tested, which the benefits of the latter over the former are demonstrated.
