Pulse-Amplitude Modulation (PAM) involves varying the signal amplitude according to the analog input signal. Pulse-Width Modulation (PWM) adjusts the width of the pulse based on the input signal, while Pulse-Position Modulation (PPM) changes the position of the pulse based on the input signal....
Luis F. Chaparro, Aydin Akan, in Signals and Systems Using MATLAB (Third Edition), 2019 8.2.1 Pulse Amplitude Modulation A PAM system can be visualized as a switch that closes every Ts seconds for Δ seconds, and remains open otherwise. The PAM signal is thus the multiplication of the con...
The article presents a model for the pulse modulation in amplitude and in width based on the minimization of the distortion coefficients and the assessment of a certain harmonic content of the synthetic voltage. The synthesis is optimal, because for a synthetic voltage in m steps, the amplitude ...
