Analog Baseband Modulation, in Modulation

Description

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

In the course of demodulating, this block uses a filter whose transfer function is described by the Lowpass filter numerator and Lowpass filter denominator parameters.

Dialog Box

Output signal offset
The same as the Input signal offset parameter in the corresponding DSB AM Modulator Baseband block.
Lowpass filter numerator
The numerator of the lowpass filter transfer function. It is represented as a vector that lists the coefficients in order of descending powers of s.
Lowpass filter denominator
The denominator of the lowpass filter transfer function. It is represented as a vector that lists the coefficients in order of descending powers of s. For an FIR filter, set this parameter to 1.
Initial phase (rad)
The initial phase in the corresponding DSB AM Modulator Baseband block.
Sample time
The sample time of the output signal.
