A series resonant band-stop filter consists of a 68 Ω resistor, a 110 mH coil, and a 0.02 µF capacitor. The internal resistance, RW, of the coil is 4 Ω. Input voltage is 200 mV. Output voltage is taken across the coil and capacitor in series. What is the output voltage magnitude at f0?

2.
Vout = 500 mV, and Vin = 1.3 V. The ratio Vout/ Vin expressed in dB is

3.
In a certain parallel resonant band-pass filter, the resonant frequency is 14 kHz. If the bandwidth is 4 kHz, the lower frequency

4.
The bandwidth of a resonant filter is determined by the quality factor (Q) of the circuit and the resonant frequency.

5.
A band-stop filter passes frequencies between its lower and upper critical frequencies and rejects all others.

6.
An RC high-pass filter consists of an 820 Ω resistor. What is the value of C so that Xc is ten times less than Rat an input frequency of 12 kHz?

7.
In a certain parallel resonant band-pass filter, the resonant frequency is 14 kHz. If the bandwidth is 4 kHz, the lower frequency is

8.
A band-pass filter rejects all frequencies within a band between a lower and an upper critical frequency and passes all others.

9.
Critical frequencies are also called -3 dB frequencies.

10.
In a series resonant band-pass filter, a lower value of Q results in
