answer a and b please thank you a. Draw the frequencyspectrum of the channelcentered on 99.9 MHz,showing all relevantfrequencies.b. Draw the frequencyspectrum of the FM band,showing details of the threelowest-frequency channelsand the three highest-frequency channels.c. Determine the bandwidthof the FM signal by usingthe deviation ratio and theBessel table.d. Determine the bandwidthof the FM signal by usingCarson's rule.e. Which of the abovebandwidth calculations bestfits the available channelbandwidth? The FM radio broadcast band is allocated the frequency spectrumfrom 88 to 108 MHz. There are 100 channels spaced 200 kHzapart. The first channel center frequency is 88.1 MHz; the last, or100th, channel center frequency is 107.9 MHz. Each 200-kHzchannel has a 150-kHz modulation bandwidth with 25-kHz"guard bands" on either side of it to minimize the effects of over-modulation.The FM broadcast band permits a maximum deviationof +/-75 kHz and a maximum modulating frequency of 15kHz. Determine the bandwidth of the FM signal using Carson'srule.

answer a and b please thank you

a. Draw the frequency
spectrum of the channel
centered on 99.9 MHz,
showing all relevant
frequencies.
b. Draw the frequency
spectrum of the FM band,
showing details of the three
lowest-frequency channels
and the three highest-
frequency channels.
c. Determine the bandwidth
of the FM signal by using
the deviation ratio and the
Bessel table.
d. Determine the bandwidth
of the FM signal by using
Carson's rule.
e. Which of the above
bandwidth calculations best
fits the available channel
bandwidth?

The FM radio broadcast band is allocated the frequency spectrum
from 88 to 108 MHz. There are 100 channels spaced 200 kHz
apart. The first channel center frequency is 88.1 MHz; the last, or
100th, channel center frequency is 107.9 MHz. Each 200-kHz
channel has a 150-kHz modulation bandwidth with 25-kHz
"guard bands" on either side of it to minimize the effects of over-
modulation.The FM broadcast band permits a maximum deviation
of +/-75 kHz and a maximum modulating frequency of 15
kHz. Determine the bandwidth of the FM signal using Carson's
rule.
