SineWaveModulated

SineWaveModulated#

class SineWaveModulated(options)#

Bases: ModulatedWaveform

SineWaveModulated generates amplitude, frequency, and phase modulated sine waves.

Creates sine wave signals with time-varying amplitude, frequency, and phase modulation. Supports complex modulation patterns for advanced signal generation and communication applications. Inherits from ModulatedWaveform.

Example1:

% Create amplitude modulated sine wave
ampMod = SineWave(frequency = 10, amplitude = 0.5);
sine = SineWaveModulated(frequency = 1000, amplitude = 1.0, ...
                         amplitudeModulation = ampMod);
sine.plot();

Example2:

% Create frequency modulated sine wave
freqMod = SineWave(frequency = 5, amplitude = 100);
sine = SineWaveModulated(frequency = 1000, amplitude = 1.0, ...
                         frequencyModulation = freqMod);
