A parallel resonant band-pass filter consists of a 6.8 resistor in series with a parallel network made up of an 8 H coil and a 120 pF capacitor. The output is taken across the capacitor/coil. Assume RW = 0 . What is the center frequency of the filter?
A series resonant band-pass filter consists of a 2 mH coil, a 0.005 F capacitor, and a 120 resistor. The winding resistance of the coil is 12 . The output voltage is taken off the resistor. Input voltage is 12 Vrms. What is the output voltage magnitude at the center frequency (f0)?
