PDM Interface Module inoshandiswa mukuyedzwa kwekuteerera kwedhijitari MEMS maikorofoni

Wedzera odhiyo analyzer yekupinda / inobuda chiratidzo chechiteshi

 

 

Pulse modulation PDM inogona kufambisa masaini nekugadzirisa density yemapulses, uye inowanzo shandiswa mukuyedzwa kwekuteerera kwedhijitari MEMS maikorofoni.

Iyo PDM module ndeye yakasarudzika module yeaudio analyzer, iyo inoshandiswa kuwedzera bvunzo interface uye mabasa eiyo audio analyzer.
