For a parallel RLC resonant circuit, the damped frequency

For a parallel RLC resonant circuit, the damped frequency is √8 r/s and bandwidth is 2 r/s. What is its resonant frequency?

Given,
_d = 8 r/s and B.W. = 2 r/s
From relation
_d = 0² – α²

where α =	B.W.
	2

or
_d² = 0² – α²
or
0² = d² + α2
or
0² = (8)² + 2/2 ²
or
0² = 8 + 1 = 9
or
0 = 3 r/s
