PDM Interface Module faʻaaogaina i suʻega leo o masini faʻalogo MEMS numera

Fa'alautele le mea e tu'u mai ai/tulaga fa'ailoga leo

 

 

Pulse modulation PDM e mafai ona tuʻuina atu faʻailoga e ala i le faʻavasegaina o le mamafa o pulus, ma e masani ona faʻaaogaina i suʻega leo o masini faʻaogaina memes.

O le PDM module o se filifiliga filifiliga o le suʻega leo, lea e faʻaaogaina e faʻalautele ai le suʻega suʻega ma galuega a le suʻega leo.
