Identification of the Memory Process in the Irregularly Sampled Discrete Time Signal of Solar Radio Flux

(Eds.)
(2013)

Abstract

n the present work, we have considered the daily signal of Solar Radio flux of 2800 Hz cited by National Geographic Data Center, USA during the period from 29 th October, 1972 to 28th February, 2013. We have applied Savitzky- Golay nonlinear phase filter on the present discrete signal to denoise it and after denoising Finite Variance Scaling Method has been applied to investigate memory pattern in this discrete time variant signal. Our result indicates that the present signal of solar radio flux is of short memory which may in turn suggest the multi-periodic and/or pseudo-periodic behaviour of the present signal.
