Module ebonakalayo ye-PDM esetshenziswa ekuhlolweni okulalelwayo kwama-microphone we-Digital Mems afakiwe Isithombe

Imodyuli ye-PDM interface esetshenziswa ekuhlolweni okulalelwayo kwama-microphones we-DIGICAL Mems

Nweba i-Audio Analyzer Input / Output Signal Port

I-USD 2,140.00

I-Pulse Moda wokuduma ingadlulisela amasiginali ngokuguqula ubuntu bama-pulses, futhi kuvame ukusetshenziswa ekuhlolweni komsindo kwemakrofoni ye-devital mems.

Imodyuli ye-PDM iyimodyuli yokuzikhethela ye-analyzer yomsindo, esetshenziselwa ukwandisa isikhombimsebenzisi sokuhlola kanye nemisebenzi ye-analiya ye-audio.
