DSB AM Modulator Baseband

Modulate using double-sideband amplitude modulation

Library

Analog Baseband Modulation, in Modulation

Description

The DSB AM Modulator Baseband block modulates using double-sideband amplitude modulation. The output is a baseband representation of the modulated signal. The input signal is real, while the output signal is complex. The input must be a sample-based scalar signal.

If the input is u(t) as a function of time t, then the output is

where:

• is the Initial phase parameter.
• k is the Input signal offset parameter.

Dialog Box

Input signal offset

The offset factor k. This value should be greater than or equal to the absolute value of the minimum of the input signal.

Initial phase (rad)

The phase of the modulated signal.
