Compare Double-Sideband and Single-Sideband Amplitude Modulation Set the sample rate to 100 Hz. Create a time vector 100 seconds long. fs = 100; t = (0:1/fs:100)'; Set the carrier frequency to 10 Hz. Generate a sinusoidal signal. fc = 10; x = sin(2*pi*t); Modulate x using si...
For Amplitude Modulation, it suppose to have carrier amplitude and modulated amplitude. however, the matlab built in function which is ammod, i cannot find which is carrier amplitude. https://uk.mathworks.com/help/comm/ref/ammod.html y = ammod(x,Fc,Fs,ini_phase) ...
Amplitude modulation (AM) is a linear baseband modulation technique in which the message modulates the amplitude of a constant frequency signal. Communications Toolbox™ software includes these modulation and demodulation functions, System objects, and blocks to model pulse amplitude modulation (PAM) an...

Mapping order for the modulation symbols, specified as'bin'or'gray'. This argument specifies how the function assigns binary vectors to corresponding integers. Ifsymorderis'bin', the function uses a binary-coded mapping order. Ifsymorderis'gray', the function uses a Gray-coded mapping order. ...
This MATLAB function demodulates the single sideband amplitude modulated signal y from the carrier signal having frequency Fc (Hz).

MATLABAnalog electronicsAnalog modulation is one of the hot topics in current research. Digital technology cannot completely replace analog technology, and analog modulation is the basic method of communication. Researchers have found and proved that the anti-noise capability of the receiver can measure...

20 have investigated the relevance of Amplitude Modulation (AM) for RVS to reduce eye fatigue. The AM approach consists in the modulation of the amplitude of the flickering signal by another oscillating signal of higher frequency (the carrier) over time. The authors concluded that AM, although ...
