PDM Interface Module e sebelisoang tlhahlobong ea molumo ea li-microphone tsa MEMS tsa dijithale

Eketsa boema-kepe ba li-audio analyzer / output signal

Pulse modulation PDM e ka fetisa matšoao ka ho fetola sekhahla sa maqhubu, 'me hangata e sebelisoa litekong tsa molumo tsa li-microphone tsa MEMS tsa digital.

Mojule oa PDM ke mojule oa boikhethelo oa mohlahlobi oa molumo, o sebelisetsoang ho holisa sebopeho sa tlhahlobo le mesebetsi ea mohlahlobi oa molumo.
