+From this previous lab on [[university:courses:alm1k:circuits1:alm-cir-lc-resonator|Parallel LC Resonance]] we can also use the formula for the LC resonance to calculate the center frequency of the band pass filter, the resonant frequency ω<sub>o</sub> is given by:
+<m>ω_o = 1/sqrt{LC }</m> rad/s
+OR
+<m>f_o = 1/(2pi sqrt{LC})</m> Hertz
