Homework Answers
for monophonic transmission
transmission banwidth = 2*(D+1)*15
where D is deviation ratio = frequency deviation/base band
so for base band of 15 kHz
bandwitdth for monophonic signal=2*(75/15+1)*15=180 KHZ
for Stereophonic FM modulated signals
base band is 53kHz so D=75/53=1.42
tnasmission bandwidth = 2*2.42*53=256.5 kHz
so it is obsereved from above calculation that bandwidth for streophonic signal is higher.
