The value of resonant frequency in the m-derived low pass filter is?(a

1.	The value of resonant frequency in the m-derived low pass filter is?(a) fr=1/(√(LC(1+m^2)))(b) fr=1/(√(πLC(1+m^2)))(c) fr=1/(√(LC(1-m^2)))(d) fr=1/(√(πLC(1-m^2)))This question was posed to me in unit test.I would like to ask this question from m-Derived T-Section topic in division Filters and Attenuators of Network Theory
Answer» Correct CHOICE is (d) fr=1/(√(πLC(1-m^2))) To explain I would say: ωr^2 = 1/(LC(1-m^2)). So the VALUE of resonant frequency in the m-derived LOW pass filter is fr=1/√(πLC(1-m^2)).
