Abstract :
This paper presents the configuration and performance of a magnetic field measuring system in Bogotá - Colombia and describes the signal processing procedure based on adaptive filters using the fractional Fourier Transform (FRFT) compared with traditional filters and the application of a numerical integration method to reduce the noise present in the recorded lightning signals.
