In part a, we're asked, what is the bandwidth? bandwidth is equal to 2 times delta f max plus fm.
00:08
So our delta f max is 1 khz, and our delta f max is 150 hertz, and fm is 1 kilohertz.
00:16
So we would have 2 times 150 plus 1 ,000, which is 2 .3 kilohertz.
00:21
For part b, we'd like to see what happens, by what factors the bandwidth increased.
00:27
So we know that we're going to have some frequency multiplication, but it's only going to, only the delta f is going to affect the bandwidth.
00:38
So bandwidth is equal to 2 times delta f max plus fm.
00:43
So it'll be 2 times 16 times 150 plus 1 ,000, which is equal to 6 .8 kilohertz...
