窄带调频 meaning in Chinese

narrow band frequency modulation
narrow frequency modulation
narrowband frequency modulation
nbfm
nfm

So it can decrease the module ' s volume , lower its power consume , what ' s more , it make it possible for demodulation of other types signal such nbfm on the same platform
这样能够在很大程度上使解调模块体积缩小、功耗降低，而且便于扩展解调其它类型的信号，例如窄带调频、短波段数据传输等。
