11bhaiyya check this one out please
i dont know the answer
An FM signal has a resting frequency of 105 Mhz and highest frequency of 105.03 Mhz ,when modulated by a signal. Then the carrier swing is?

so dont worry about these type of probs[1]
62carrier swing
(communications) The total deviation of a frequency-modulated or phase-modulated wave from the lowest instantaneous frequency to the highest instantaneous frequency.
This term I had never heard.. Nor do I think it is in syllaubs.
Q) what will coaching institutes do if there are very smart students and they need to prove that they are good and have too much knowledge?
A) "Give something not in syllabus" :D
So this is one of those examples...
24i can be wrong too..........so keep trying...........
we will have to wait for confirmation from Nishant sir
24well i only know the definiton,.............i have never done any sum on this one........this is my first try.............
i still think a)
11well i answered 0.06 because i thought it could go below 105 like 104.7
so 105.03-104.97=0.06
1eureka........carrier wave always has higher frequency than signal rite???
24becoz it is the total deviation of a frequency-modulated wave from the lowest instantaneous frequency to the highest instantaneous frequency.
1i dunno wat d heck resting frequency is.....but d highest freq is carrier + signal freq=105030 Khz....
assuming resting freq is minimum......then carrier freq is 105015 KHz..
( and wat is carrier swing???)
