Oct 14, 2013 · Amplitude modulation (AM) is a one of the conventional modulation technique to transmit signals using a carrier wave. The amplitude or the strength of a high frequency carrier wave is changed in accordance with the amplitude of message signal.

May 29, 2021 · Amplitude modulation in MATLAB can be achieved by using the ammod() function. ammod() Syntax : y = ammod(x, Fc, Fs, ini_phase, carramp) Parameters : x : amplitude signal; Fc : carrier signal frequency; Fs : sampling frequency; ini_phase : initial phase in the modulated signal y in radians; carramp : carrier amplitude of the modulated signal

Mar 28, 2018 · MATLAB code for amplitude modulation and demodulation using functions ammod and amdemod.

These examples demonstrate amplitude modulation (AM) techniques. In this example, you generate a random digital signal, modulate it, add noise, demodulate the noisy signal, and compute the symbol error rate. Then you plot the noisy, modulated data in a constellation diagram. The numerical results and plot may vary due to the random input data.

The Amplitude Modulation Analysis Toolbox, for MATLAB / Octave, provides functions to compute and visualize the time-frequency and frequency-frequency domain representations of real signals. The Python 3 version of this toolbox can be found here: https://github.com/MuSAELab/amplitude-modulation-analysis-module

ASK modulation is a digital modulation scheme that varies the amplitude of a carrier signal to transmit digital information. The code in this repository demonstrates ASK modulation and includes functionalities for modulation and demodulation.
