PDM Interface Module yogwiritsidwa ntchito poyesa ma audio pama maikolofoni a digito a MEMS Chithunzi Chowonetsedwa

PDM Interface Module yomwe imagwiritsidwa ntchito poyesa ma audio pama maikolofoni a digito a MEMS

Wonjezerani audio analyzer input / output sign port

Pulse modulation PDM imatha kutumiza ma siginecha posintha kuchuluka kwa ma pulse, ndipo imagwiritsidwa ntchito poyesa ma audio pama maikolofoni a digito a MEMS.

Module ya PDM ndi gawo losankha la audio analyzer, yomwe imagwiritsidwa ntchito kukulitsa mawonekedwe oyesera ndi ntchito za audio analyzer.
