Analog Baseband Modulation, in Modulation

Description

The SSB AM Demodulator Baseband block demodulates a signal that was modulated using single-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, the block uses a filter whose transfer function is described by the Lowpass filter numerator and Lowpass filter denominator parameters.

Dialog Box

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 SSB AM Modulator Baseband block.

Sample time

The sample time of the output signal.
