The asymptotic magnitude Bode plot of a minimum phase system is shown in the figure. The transfer function of the system is 
, where 
and c are positive constants. The value of 
is __________. (rounded off to the nearest integer).
Explanation:
From the given Bode magnitude plot, it is clear that there is one pole at origin, so we get 
so 
and at frequency 
As the slope is 
decade previously to make it 0 slope we will need a zero at frequency , so 
system has a zero,
and at frequency 
,
As the slope is 
decade previously to make it 
decade slope we will need 2 poles at frequency , so
