if there are two solenoids d(cm) apart from each other (in 3D environment[x y z]); in other words, they are not laid on the same axis and the difference between the value of x and y and z (for S1 and S2) is not zero (see Figure please)
what would be the mutual inductance (M)?
or the coupling...
according to this plot the bandwidth at 10MHz is 2kHz! (where 3dbBW=1kHz)
while according to the Shannon Equation:
the bandwidth is (3db_Bandwidth * f), which in this case will be: 1khz*10Mhz
?!
thank you for your reply.
according to the plot, if the 3db bandwidth is 4khz, the total bandwidth around the frequency (for example : 10Mhz) is 8Khz.
however according to the Shannon theorem, the bandwidth is (3db_Bandwidth * f), which is this case will be: 4khz*10Mhz.
these two values are...
If we want to determine the bandwidth at a given frequency f, we should determine the 3dB fractional bandwidth.
according to the Shannon formula, we can calculate the bandwidth to be:
Bandwidth at f =3db_Bandwidth*f
on the other hand when plot the frequency vs received power to determine the...
capacity of a communication link and QPSK modulation
does any body know the capacity of a communication link based on QPSK modulation;
how is it related to the Shannon theorem?
does any body know how I can define the capacity of a communication link based on QPSK modulation?
does it have any thing to do with the Shannon Theorem?
