DSBSC AM Modulator Passband
Modulation using amplitude modulation with two sidebands and suppressed carrier frequency.
Description
The DSBSC AM Modulator Passband unit performs modulation using dual sideband amplitude modulation with suppressed carrier frequency (DSBSC AM). The output is a passband representation of the modulated signal. The input and output signals are real scalar signals.
If the input is a signal as a function of time-dependent, the output is:
,
where
-
- carrier frequency, the value of Carrier frequency (Hz);
-
- initial phase, value of parameter Initial phase (rad).
As a rule, a suitable value of Carrier frequency (Hz) is much higher than the highest frequency of the input signal. By Kotelnikov’s theorem, the inverse of the sampling period of the model (determined by the source of the model signal) must be greater than twice the Carrier frequency (Hz).
This block works only with real inputs of Float64 type. This block does not work inside the trigger subsystem.
