  • Moderi ya PDM ikoreshwa mugupima amajwi ya mikoro ya MEMS

Moderi ya PDM ikoreshwa mugupima amajwi ya mikoro ya MEMS

Kwagura isesengura ryamajwi yinjiza / ibisohoka byerekana icyambu

 

 

Guhindura pulse PDM irashobora kohereza ibimenyetso muguhindura ubwinshi bwimisemburo, kandi ikoreshwa kenshi mugupima amajwi ya mikoro ya MEMS ya digitale.

Module ya PDM ni module idahwitse yisesengura ryamajwi, ikoreshwa mukwagura ibizamini nibikorwa byisesengura amajwi.
