1.
A band-stop filter passes frequencies between its lower and upper critical frequencies and rejects all others.
2.
The bandwidth of a resonant filter is determined by the quality factor (Q) of the circuit and the resonant frequency.
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.
Vout = 500 mV, and Vin = 1.3 V. The ratio Vout/ Vin expressed in dB is
5.
In a series resonant band-pass filter, a lower value of Q results in
6.
Critical frequencies are also called -3 dB frequencies.
7.
A band-pass filter rejects all frequencies within a band between a lower and an upper critical frequency and passes all others.
8.
In a certain parallel resonant band-pass filter, the resonant frequency is 14 kHz. If the bandwidth is 4 kHz, the lower frequency is
9.
An RC high-pass filter consists of an 820 O resistor. What is the value of C so that Xc is ten times less than Rat an input frequency of 12 kHz?
10.
The same signal in Problem 2 is applied to an RC high-pass filter. If the reactance is zero at the input frequency, the output voltage is
