Sažetak
In this paper a novel numerical method is proposed for solving the Fourier transform of an arbitrary transient function. Fourier integral is solved using a combination of numerical and analytical integration resulting in a continuous transient function in the frequency domain. The proposed numerical algorithm enables robust and accurate transformation of any arbitrary transient function into the frequency domain. This also includes arbitrarily sampled measured lightning currents. The result of the transformation in the frequency domain is continuous and completely independent of the time domain sampling procedure unlike in transformation algorithms that are generally employed for this purpose. Accuracy of the proposed algorithm has been verified on a number of numerical examples.
