send analog signal on AM

[yehonatan]

hello,
It is passable to send a signal on AM modulation in 2.4Ghz frequency carrier.
if YES what are the problem that can be occur?

thanks

Sounds like that could be a homework problem.

Think about this: Is there anything else besides the
signal that could influence the amplitude of the
carrier wave in the receiving circuit?

dir jim,
I know there is noise that can influance, but the same noise is in the
low frequency. so i don't understand the different of the noise in
these two range.
maybe the problem is in the inplementation of the circuit(RC value)?
thank for answer

Same problems that can occur at ANY frequencey, just that they might
be more pronounced or more difficult to fix. 2.4Ghz wont propogate as
far as 1Mhz at the same power, for example.

Unquestionably more expensive/difficult to do @ higher freq. but not
impossible.
Perhaps less to do with the difference in the noise, and more to do
with the difference in the C/N ratio...

In and of itself, there is nothing wrong with doing AM at that (or
any) frequency. You'll find, though, that this is what is known as a
"junk" band. I't the frequency that microwave ovens work at, so
there all sorts of noise from those things in that band. Also, this
is the resonant frequency of water (thus microwave ovens), so signal
attenuation is quite high.
