Modulation Terminology
Modulation is a process by which a carrier signal is
altered according to information in a message signal.
The carrier
frequency, denoted Fc, is the frequency
of the carrier signal. The sampling rate is the rate at which
the message signal is sampled during the simulation.
The frequency of the carrier signal is usually much greater
than the highest frequency of the input message signal. The Nyquist
sampling theorem requires that the simulation sampling rate Fs be
greater than two times the sum of the carrier frequency and the highest
frequency of the modulated signal in order for the demodulator to
recover the message correctly.
