Final answer:
The Q factor of the band-pass filter can be calculated as the ratio of the center frequency to the difference between the low and high cut-off frequencies. In this case, the Q factor is 1.37.
Step-by-step explanation:
The Q factor of a band-pass filter is a measure of its efficiency in allowing a specific range of frequencies to pass through while attenuating others.
It is defined as the ratio of the center frequency to the difference between the low and high cut-off frequencies. In this case, the center frequency is the geometric mean of the low and high cut-off frequencies.
To find the Q factor, we can use the formula Q = fc / (f2 - f1), where fc is the center frequency and f1 and f2 are the low and high cut-off frequencies respectively.
Using the given values, we can calculate the Q factor as follows: Q = 46 kHz / (60 kHz - 32 kHz) = 1.37.
Therefore, the correct answer is B. 1.37.
