The correct answer is:
10
10
Given, modulating frequency $f_m$ $=15 \mathrm{KHz}$
$\therefore \quad$ Bandwidth of one channel $=2 f_m=30 \mathrm{kHz}$
$\therefore \quad$ No of channels accommodate
$$
=\frac{300 \mathrm{kHz}}{30 \mathrm{kHz}}=10
$$
$\therefore \quad$ Bandwidth of one channel $=2 f_m=30 \mathrm{kHz}$
$\therefore \quad$ No of channels accommodate
$$
=\frac{300 \mathrm{kHz}}{30 \mathrm{kHz}}=10
