Modulation means changing something in a controlled, smooth way rather than suddenly. When you speak, modulation is how you change your voice's pitch, speed, and loudness so you don't sound flat and boring. In music, modulation means moving from one key to another through a song. In radio and electronics, modulation is how a signal is changed to carry sound or data — 'FM' radio literally stands for 'frequency modulation.'
調節、調變；廣播中的「調頻」（FM）就是 frequency modulation。
