Question

A circuit resonates at 1 MHz It also has a Q of 100. Bandwidth between half power points is _____________

(a) 10 kHz

(b) 100 kHz

(c) 10 Hz

(d) 100 Hz

Answer 1

Right choice is (a) 10 kHz

To explain I would say: We know that, Q = (frac{f}{∆f})

Or, ∆f = (frac{f}{Q})

 = (frac{10^6}{100}) = 10 kHz.
