Question 707 Explanation:
Ch1 – gb -ch2-gb-ch3-gb-ch4-gb-ch5-gb-ch6-gb-ch7-gb-ch8-gb-ch9-gb-ch10. Where Ch represents channel and gb means guard bands.
There are total 10 channels and 9 guard bands.Each guard band is 300Hz wide
9 guard band occupies 2700 hz.
10 channels occupies 30000 hz.
So total bandwidth is 32700.
