This MATLAB function returns the complex envelope of the modulation of the input message signal, x, using PAM and the alphabet size, M.
Apply pulse amplitude modulation (PAM) to the generated data. Get modData = pammod(dataIn,M); Apply pulse amplitude demodulation to the modulated data. Get demodData = pamdemod(modData,M); Compare the first five symbols. Get [dataIn(1:5) demodData(1:5)] ans = 5×2 6 6 7 ...

The comm.PAMDemodulator System object™ demodulates a signal that was modulated using M-ary pulse amplitude modulation (M-PAM) method. The input is a baseband representation of the modulated signal. To demodulate a signal that was modulated using M-PAM method: Create the comm.PAMDemodulator ob...
Matlab-pulse generator-讲解 各个参数说明: amplitude:脉冲高度; period:周期时间(单位:秒) pulse width:脉冲宽度占一个周期的百分比 phase delay:相位延迟时间,即定义脉冲初始相位角度。如果是0代表仿真开始就发送脉冲。... 查看原文 电力电子技术1:单相半波电路电阻负载simulink仿真,详解 library b’rowser库,...
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....
We preprocessed the recorded EMG segments with a custom MATLAB script. The segments were first bandpass-filtered at 20–500 Hz in both directions with a 2nd-order Butterworth filter. Then, we applied a spectrum interpolation filter to remove the line noise at 50 Hz [24]. We visually inspected...

The latter modulates data on the timing attributes of pulses with binary amplitude levels. According to the common terminology in digital communications, pulse-time modulation techniques are categorized under line encoding techniques (sometimes referred to as baseband modulation schemes as well).
