Homework Statement
calculate the frequency deviation using an approximate technique
Homework Equations
input analogue signal is 1.2kHz
min bandwidth to avoid over-sampling is 3.6kHz
signal transmitted over 1.1km with a 12kHz bandwidth on a FM carrier
Carrier freq is in the GSM reverse band at 875MHz
The Attempt at a Solution
Bandwidth requirement (CBR) =2(Δf + fm)
0.5CBR - fm= Δf = freq deviation
does CBR=12kHz and fm=875MHz?
Don't know what goes where
