Amplitude modulation and demodulation is implemented with basic equations. It can be run without having communication toolbox.Cite As Ashwini (2025). AM Mod-Demod (https://www.mathworks.com/matlabcentral/fileexchange/25885-am-mod-demod), MATLAB Central File Exchange. Retrieved May 19, 2025. ...
VSB-AM modulation and demodulation mode and that demodulatorPURPOSE:To execute accurate carrier recovery even at overmodulation by operating a phase locked loop circuit for carrier recovery for a specific period before and after a midpoint of a horizontal drive waveform of a television signal while ...
For the performing AM modulation, we need to give importance when we select A, especially when checking the envelope detection. In MATLAB code, it is properly selected as 0.5, and the carrier frequency is chosen as 10 kHz, which is higher than the bandwidth of the message signal since ...

The source-filter model assumes that the sound source for the voiced speech is localized in the larynx and the vocal tract acts as a convolution filter for the emitted sound. Examples of phenomena not well-captured by the source-filter model include unstable airflow, turbulence and nonlinearities...
