DSBSC AM Modulator Passband Purpose 4DSBSC AM Modulator Passband Library Analog Passband Modulation, in Modulation Description 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 sample-based scalar signals. Modulate using double-sideband suppressed-carrier amplitude modulation If the input is u(t) as a function of time t, then the output is u(t) cos(2πfct+θ) 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. To avoid having to use a high carrier frequency and consequently a high sampling rate, you can use baseband simulation (DSBSC AM Modulator Baseband block) instead of passband simulation. Dialog Box Carrier frequency (Hz) The frequency of the carrier. Initial phase (rad) The initial phase of the carrier in radians. Pair Block DSBSC AM Demodulator Passband 4-183
