Its purpose is to attenuate higher frequencies while allowing lower frequencies to pass through. A 830-Hz sine-wave signal with rms amplitude of Vs 2.8 V is fed into the filter The values of the components are R 0.56 ? and L 110 ??.

Hints remaining: S ? 50% Part (b) By what angle, in degrees, does the output voltage lag the input voltage?Explanation / Answer
R = 0.56 ohm
and XL = 2 pi f L = 2 x pi x 830 x 110 x 10^-6
xL = 0.574 ohm
Z = sqrt[ R^2 + XL^2] = 0.802 ohm
(A) I_rms = V_rms / Z = 3.49 A
V_out = I_rms R = 1.96 Volt
(B) phi = tan^-1(0.574 / 0.56) = 45.7 deg
