Hi Group, What is the mechanism for the way radio signals combine in the air? For example 1.There are two transmitters each sending out the same fixed frequency sine wave signal. 2. There are no othe
Hi Edgar.......Or if the receiver is operating in a linear mode.....then straight addition, but probably only with SSB detection, an AM demodulater diode is non-linear :-)) If you add the signals com
Edgar, straightforward linear addition of voltages. If both transmitters had same power and phase you will get + 6 dB on the receiver. If you had two equally (in)efficient LF antennas on the same pre
Hmmm! Interesting one. I have always assumed that the first point at which the signal(s) caused the electromagnetic field(s) to develop into voltages/currents and might then be subject to further pro
The short answer is 'No they have not' There is no interference in free space unless you transgress into partial physics and then the theories are held together with string , there is that experiment
...will be the vector sum of the two carriers / time and for a spectrum , then a reference is needed to recover the modulation , CIO , to give freq/amp/time , or a complex w/f / time for a detector a
that dose something funny with a low frequency modulation to give a ' rotating ' field , where the phase gives the bearing ? G, ...will be the vector sum of the two carriers / time and for a spectrum
