In a series resonant band-pass filter, a lower value of Q results in
In an RL low-pass filter, the output voltage is taken across the inductor and the output lags the input.
In an RL high-pass filter, the output is taken across the inductor and the output leads the input.
The maximum output voltage of a certain low-pass filter isV. The output voltage at the critical frequency is
A band-pass filter rejects all frequencies within a band between a lower and an upper critical frequency and passes all others.
In an RC high-pass filter, the output is taken across the resistor and the output leads the input.
A band-stop filter passes frequencies between its lower and upper critical frequencies and rejects all others.
Critical frequencies are also called –3 dB frequencies.
The output voltage is 63.of its maximum at the critical frequencies.
The bandwidth of a resonant filter is determined by the quality factor (Q) of the circuit and the resonant frequency.
A parallel resonant band-pass filter consists of a resistor in series with a parallel network made up of amH coil and a 0.F capacitor. The output is taken across the capacitor/coil. The coil winding has a resistance of. What is the center frequency of the filter?
