Module Interface PDM oo loo adeegsaday tijaabinta maqalka ee makarafoonnada dhijitaalka ah ee MEMS Sawirka

Module Interface PDM ayaa loo isticmaalay tijaabada maqalka ee makarafoonada MEMS ee dhijitaalka ah

Balaadhi gelinta/samaynta falanqeeyaha maqalka dekedda

Hababka garaaca wadnaha PDM waxay gudbin kartaa calaamadaha iyadoo wax ka beddelaysa cufnaanta garaaca wadnaha, waxaana badanaa loo adeegsadaa tijaabinta maqalka ee makarafoonnada MEMS ee dhijitaalka ah.

Qaybta PDM waa cutubka ikhtiyaariga ah ee falanqeeyaha maqalka, kaas oo loo isticmaalo in lagu ballaariyo isdhexgalka tijaabada iyo hawlaha falanqeeyaha maqalka.
