here is all the code in matlab for the modulation and demodulation in FM and PM where the input is the voice and show step by step the process in the modulation

相位的调制，可以改变调制信号频率，观测已经调制波形-Phase modulation, can change the frequency of modulation signal, the observation has been modulated waveform

labview PM模拟调制模块，需下载ni modulation toolkits，ni官网可免费下载-labview PM analog modulation modules need to download ni modulation toolkits, ni official website can be downloaded for free

labveiw实现基带信号的幅度调制（AM），频率调制(FM)和相位调制(PM)，可以在波形图中看到调制信号和调制后信号的叠加和对比，可以看到频域波形。载波与基带幅度和频率参数均可改变。-Baseband AM/FM/PM in labview. In the vi, you ll be able to see the modulated signal in both time and frequency domain.
