There are various definition's for quality factor
basic def is 2*pi*(stored energy/dissipated energy per cycle)
.In case if the circuit don't have dissipative elements then
use Q=(center frequency/3db bandwidth).If the circuit wont
oscillate then use (imaginary term/real term).
coming to how Q should be ideally
1.In case of filter
.707 for max flatness,.5 for no
oscillation's,1/sqrt(3)for max flt group delay.
2.For oscillators nad Bandpass filters Q should be as max
as possible
3.for amplifiers q should be as low as possible inorder to
get good step response.
Hope you learn some thing
Thank you,
