If the Q of a bandpass filter is less than 1,it is called a
A) wideband filter.
B) narrowband filter.
C) notch filter.
D) low-pass filter.

Question

Quizplus · Accepted Answer

The Q factor is a measure of the bandwidth of a filter. A Q value of less than 1 indicates that the filter has a wider bandwidth than that of the center frequency it is tuned for. Therefore, the correct choice would be a wideband filter (Option A) as it allows a range of frequencies to pass through. Narrowband filters (Option B) have higher Q values and allow only a narrow range of frequencies to pass through. A notch filter (Option C) is designed to block a specific frequency, and a low-pass filter (Option D) allows frequencies below a certain cutoff frequency to pass through.
