Q. In the above question, if oscillator output is modulated by audio frequencies upto 10 kHz, the frequency range occupied by the side bonds will be

A) 711.9 kHz to 712.1 kHz
B) 692 kHz to 732 kHz
C) 702 kHz to 722 kHz
D) 71.2 kHz to 70.2 kHz
Explanation

(c) Here, $f_{m} = 10\ kHz$
$\therefore f_{SB} = f_{c} \pm f_{m} = (712 \pm 10) = kHz$
$= 702\ kHz\ and\ 722\ kHz$
