Resonant frequency = G.M(geometric mean) of f1 & f2.
fr = root of (f1 & f2).
For High quality factor circuits Q >> 5, ckts approximately A.M of f1 & f2. fr = 0.5(f1 + f2).
fr = root of (f1 & f2).
For High quality factor circuits Q >> 5, ckts approximately A.M of f1 & f2. fr = 0.5(f1 + f2).

B.W = f2-f1 = 4hz.
fr^2 = f1*f2 = 196.
By solving above eq...f1 = 12hz.
fr^2 = f1*f2 = 196.
By solving above eq...f1 = 12hz.

The resonant frequency is 14 kHz.
Band Width is 4 KHz.
High frequency = resonant frequency+B.w/2, So Hf = 14+4/2 = 16.
Lower frequency = resonant frequency-B.w/2, So Lf = 14-4/2 = 12.
Answer C.
Band Width is 4 KHz.
High frequency = resonant frequency+B.w/2, So Hf = 14+4/2 = 16.
Lower frequency = resonant frequency-B.w/2, So Lf = 14-4/2 = 12.
Answer C.

The resonant frequency is 14 kHz.
Band Width is 4 KHz then multiply the band width with 4.
4KHz * 4= 16KHz.
High frequency is below the 4KHz and Low Frequency is Near the 16KHz then the resultant Low Frequency is 12KHz.
Band Width is 4 KHz then multiply the band width with 4.
4KHz * 4= 16KHz.
High frequency is below the 4KHz and Low Frequency is Near the 16KHz then the resultant Low Frequency is 12KHz.
