#X text 33 60 We can modulate the amplitude of any signal (called the
"carrier" signal) by multiplying it by any oscillating signal (called
"modulator" signal). The modulating signal is usually an oscillator
\, whose frequency is the modulating frequency., f 51;
#X text 425 62 Here we have an amplitude modulation example where both
the carrier and modulator signals are sine wave oscillators. This is
"classic" amplitude modulation because the modulator signal has a DC-Offset
so that it is "unipolar" and only has positive values (from 0 to 1).
