查询词典 frequency modulation

frequency modulation：调频

这个思路就是载波,不仅调幅可以载波,而且调整频率或者调整相位也可以载波. 所以,调频(Frequency Modulation)技术的出现是顺理成章的后续发展. 1933年,调频技术专利由美国人Edwin Armstrong获得[2].

frequency modulation：频率调制

而有意思的voice的声音来自于发音物体的谐振,然后于频率调制(frequency modulation)与调辐(amplitude modulation)的变化达到有意思的sound. 燕声可没有那么复杂,基本上是要表达感觉的沟通. 它的谐振频率在4~5KHz左右飘移,
