I-PDM Interface Module esetshenziswa ekuhlolweni komsindo kwemibhobho yedijithali ye-MEMS

Nweba imbobo yesignali yokufaka yokuhlaziya umsindo

I-PDM ye-Pulse modulation ingadlulisela amasignali ngokushintsha ukuminyana kwama-pulses, futhi kuvame ukusetshenziswa ekuhlolweni komsindo kwemibhobho yedijithali ye-MEMS.

Imojula ye-PDM iyimojula yokuzikhethela yesihlaziyi somsindo, esetshenziselwa ukwandisa isixhumi esibonakalayo sokuhlola nemisebenzi yokuhlaziya umsindo.
