Vibration analysis has long been used for the detection and identification of machine fault conditions. The specific characteristics of the vibration spectrum that are associated with common fault conditions are quite well known, e.g. the BPOR spectr

The selection and preprocessing of features are crucial to the success of a classifier for pattern recognition applications. The preprocessing often involves filters, transformations and non-linear processing of the raw data. Since the training data

One of the first operations in seismic signal processing system is to distinguish between valid and invalid records. Since valid signals are characterized by a combination of their time and frequency properties, wavelets are natural candidates for de

The design of digital filters involves the consideration of various factors to achieve a satisfactory result. The complexity of implementation, sensitivity of the transfer function with respect to coefficient quantization (c.q.), and product quantiza
