Module Interface PDM ejiri na nnwale ọdịyo nke igwe igwe MEMS dijitalụ

Gbasaa ọdụ ụgbọ mmiri mgbama ntinye / mmepụta ihe nyocha

 

 

PDM modulation pulse nwere ike ibunye mgbaama site n'ịgbanwe njupụta nke usu, a na-ejikarị ya na nnwale ọdịyo nke igwe igwe MEMS dijitalụ.

PDM modul bụ nhọrọ nhọrọ nke ihe nyocha ọdịyo, nke a na-eji gbasaa nyocha ule na ọrụ nke nyocha ihe ọdịyo.
