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 collapse all in page Syntax y = ammod(x,Fc,Fs) y = ammod(x,Fc,Fs,ini_phase) y = ammod(x,Fc,Fs,ini_phase,carramp)Description y = ammod(x,Fc,Fs) returns an amplitude modulated (AM) signal y, given the input message signal x, where the carrier signal has freq...
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...
This MATLAB function returns the complex envelope of the modulation of the input message signal, x, using PAM and the alphabet size, M.

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...
(vestigial-sideband amplitude modulation). The dependence between the modulating signal and the amplitude of the modulated carrier can be very simple, as, for example, in the DSB-AM case, or much more complex, as in SSB-AM or VSB-AM. Amplitudemodulation ...
The comm.RectangularQAMTCMDemodulator System object object uses the Viterbi algorithm to decode a signal modulated by the trellis-coded modulation (TCM) technique with a rectangular quadrature amplitude modulation (QAM) signal constellation.
