AM Modulation
1. What is the main feature in AM modulation, that is used to
judge if the modulation is good or not? Explain with
examples.
2. Can AM modulated signal change phase and/or frequency?
Explain the reason.
3. What is modulation index? Its formula?
4. Plot an AM modulated signal, that has an information signal
m(t) = 10 sin(10nt) and a carrier signal
c(t) = 15
cos(1000t). Calculate the modulation index (u). Is it a good
modulation? If no, suggest a change in one of the signals
above and calculate u again, so that it approaches ideal case.
