Hi guys,
Need some help and guidance here, I'm having some difficulty(and confused) trying to understand Modulation in telecommunication systems.
From what I understand (pls correct me if I am wrong);
AM - the amplitude changes, but not the frequency.
FM - the frequency changes, but not the amplitude.
Is it true that the spectrum for AM would be the total(sum) of the spectra formed by each of the modulating signals?
What about FM ?
