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/h
Compare Double-Sideband and Single-Sideband Amplitude Modulation Copy Code Copy Command Set the sample rate to 100 Hz. Create a time vector 100 seconds long. Get fs = 100; t = (0:1/fs:100)'; Set the carrier frequency to 10 Hz. Generate a sinusoidal signal. Get fc = 10; x = ...
Quadrature Amplitude Modulation with Bit Inputs Copy Code Copy Command Modulate a sequence of bits using 64-QAM. Pass the signal through a noisy channel. Display the resultant constellation diagram. Set the modulation order, and determine the number of bits per symbol. Get M = 64; k = log...

For integer inputs, outputYhas the same dimensions as input signalX. For bit inputs, the number of rows inYis the number of rows inXdivided by log2(M). Data Types:double|single|fi|int8|int16|uint8|uint16 Complex Number Support:Yes ...
The most common strategy for controlling the power transmitted to the load is the intersective Pulse Width Modulation (PWM). A control voltage vm is compared to a triangular voltage vt. The triangular voltage vt determines the switching frequency ft. The switch T is controlled according to the ...
Any multilevel modulation scheme can be generated, but we illustrate specifically, the multilevel amplitude and differential phase shift keying (MADPSK) signals. The driving voltage levels are estimated for driving the traveling wave electrodes of the modulator. Phasor diagrams are extensively used to...
