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.
