can anybody define FM plz?
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

It is when the carrier wave frequency is modulated according to the displacement of the signal wave. Am I right?can anybody define FM plz?
in 9s very little decay of barium..since its half life is 1080s...http://www.xtremepapers.com/CIE/International A And AS Level/9702 - Physics/9702_w07_qp_4.pdf
How do you do 7c)
please help!!
i got it as ...f of carrier waves varies in (synchrony ) with signal in (synchrony) with displacement of signal...It is when the carrier wave frequency is modulated according to the displacement of the signal wave. Am I right?
First things first: Dear Moderators,
I have been facing difficulty when it comes to finding A2 posts at the threads you have so kindly created for a more organized look. However, I wanted to see a separate thread for A2 questions and A2 questions alone. So, I came up with this thread.
Truth be told, A2 is very different from AS and the queries related to them are entirely different since there are different topics involved. I hope you understand.
My first A2 question: Can anybody please explain to me what 'infinite input impedance' means?
means infinite input resistance...The pd across the input terminal is high and the current is low..
means infinite input resistance...
range of frequencies , where the maximum frequency is subracted from the lowest frequency!ppl plz define bandwidth...
cant we define it llike this...the capacity of electricle signal at which information is transfered...?range of frequencies , where the maximum frequency is subracted from the lowest frequency!
in 9s very little decay of barium..since its half life is 1080s...
for Kr in zero second its no. is x...wen it becomes half in 3s it becomes x/2..in 6s its x/4..in 9s its x/8...
so from ratio ba/kr...x/(x/8)=8...
hope u get it
i would not use this, maybe you can top it. but dont use it alone just to be on the same side.cant we define it llike this...the capacity of electricle signal at which information is transfered...?
u welcome...Thank you!!
Was Struggling a lot with this question..
y have to be subtracted from the lowesr f only?range of frequencies , where the maximum frequency is subracted from the lowest frequency!
remember the sidebands? Bandwidth is highest freq ( fc+fm) - lowest freq (fc - fm ) = 2fm = bandwidhty have to be subtracted from the lowesr f only?
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
