Abstract : A signal phase pattern sensitive neural network system can discern persistent patterns of phase in a time varying or oscillatory signal. The system employs duplicate inputs from each of its sensors to the processing clements of a first layer of its neural network, with the exception that one input is phase shifted relative to the other. The system also employs a modification of a conventional Kohonen competitive learning rule which is applied by the processing and learning elements of a second layer of its neural network.
