PM Modulator Baseband

Modulate using phase modulation

Library

Analog Baseband Modulation, in Modulation

Description

The PM Modulator Baseband block modulates using phase 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 and K_c is the Modulation constant parameter.

Dialog Box

Initial phase (rad)

The phase of the modulated signal when the input is zero.

Modulation constant (Radians per volt)

Modulation constant K_c.
