ABSTRACT:
A measurement technique that generates a number value identifying the width of a noisy pulse in an analog signal that has particular application for determining whether a defect exists in a cylinder valve of a locomotive diesel engine. The algorithm samples the analog signal, and then the samples are bunched into successive groups where each group includes a predetermined number of samples. A root mean square is taken of the samples in each group to generate a representative amplitude value for that group. Successive amplitude values are multiplied together to generate product values. The product values are averaged over a predetermined number of product values to generate the number value that can be analyzed to determine if a defect in a valve exists.
