Figure 6. Y expression versus normalized time.
The top plot shows the percentage delay in 
signal with respect to the 
signal, for varying period of oscillation 
and threshold value 
, the bottom plot shows the percentage duration of the 
signal. For values of the threshold 
lower than the average value of 
, decreasing the period of oscillation causes a faster response (lower delay) and a higher duration of 
(that eventually is active all the time when the period is small enough). For values of the threshold 
higher than the average value of 
, 
is usually delayed and of short duration, decreasing the period of oscillation causes the maximum value of 
to fall below 
leading to no activation of 
. For the plots the parameters 
, 
, 
have been used.
