摘要： Methods, systems and computer program products for performing hybrid defect detection are disclosed. A hybrid defect detection mechanism may be used to detect various classes of defects (e.g., long and shallow defects, and short and deep defects) while reducing the probability of a miss or false alarm. In some implementations, the hybrid defect detection mechanism may utilize defect detectors to each receive signal samples and apply a different set of parameters indicating a different respective window to the signal samples. Each defect detector may generate a corresponding output based on a count of signal samples within the corresponding window that are associated with abnormal signal quality.

A hybrid defect detection mechanism may be used to detect various classes of defects (e.g., long and shallow defects, and short and deep defects) while reducing the probability of a miss or false alarm. In some implementations, the hybrid defect detection mechanism may utilize a defect detector that includes one or more defect sub-detectors. Each defect sub-detector may be associated with an individual threshold and sliding window length to enhance the hybrid defect detection process that maximizes the detection of a specific type or class of defects.

摘要： System and methods are provided for signal processing. For example, an input signal is received at a finite impulse response filter circuit including a plurality of stages, where each stage of the plurality of stages is associated with a sample value of the input signal and a stage weight. An output signal is generated using the finite impulse response filter circuit, the output signal being equal to a weighted sum of the sample values of the input signal. An error signal is generated to indicate a difference between the output signal and a target. A constraint is applied to one or more of the stage weights. The stage weights are changed within the constraint to reduce a magnitude of the error signal.

摘要： Various method and system embodiments of the present invention are directed to computational estimation of a tempo for a digitally encoded musical selection. In certain embodiments of the present invention, described below, a short portion of a musical selection is analyzed to determine the tempo of the musical selection. The digitally encoded musical selection sample is computationally transformed to produce a power spectrum corresponding to the sample, in turn transformed to produce a two-dimensional strength-of-onset matrix. The two-dimensional strength-of-onset matrix is then transformed into a set of strength-of-onset/time functions for each of a corresponding set of frequency bands. The strength-of-onset/time functions are then analyzed to find a most reliable onset interval that is transformed into an estimated tempo returned by the analysis.
