Question

Verified Solution • 2025–26 Session moderate

If the highest frequency modulating a carrier is 5 kHz, then the number of AM broadcast stations accommodated in a 90 kHz bandwidth are _________.

Accepted Answer

B. W. (Bandwidth) = 2

\times

maximum frequency at modulating signal

= 2

\times

5kHz

= 10 kHz

\therefore

No of stations accommodate

=

{{90} \over {10}}

= 9
