The DSBSC AM Modulator Passband block modulates using double-sideband suppressed-carrier amplitude modulation. The output is a passband representation of the modulated signal. Both the input and output signals are real scalar signals.
If the input is u(t) as a function of time t, then the output is
where fc is the Carrier frequency parameter and θ is the Initial phase parameter.
Typically, an appropriate Carrier frequency value is much higher than the highest frequency of the input signal. By the Nyquist sampling theorem, the reciprocal of the model's sample time (defined by the model's signal source) must exceed twice the Carrier frequency parameter.
This block works only with real inputs of type double. This block does not work inside a triggered subsystem.
