Abstract
A method for determining anomalies in a line which is to be investigated detects a signal reflected from the line when a signal in the form of a pulse is applied to the line. In order to be able to carry out this method particularly quickly and with high accuracy, a weighting function is formed having a time profile that is characteristic of the response of a line which is of the same type as the line to be investigated, when it is acted on in the form of a pulse. The line which is in each case to be investigated has a single pulse applied to it as an application in the form of a pulse, and the detected, reflected signal is weighted with the weighting function in a convolution operation.
