Ukuhlolwa Komphumela We-Doppler we-LMEC-19

Incazelo emfushane:

Ukulinganisa umphumela we-doppler kanye nesivinini somsindo. Ukusetshenziswa kweyunivesithi okuseqophelweni eliphezulu.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Ukuhlolwa
1. Imvamisa yokuzwakala kwe-transducer ye-ultrasonic;
2. Ukulinganisa umphumela we-Doppler
3. Ijubane lomsindo lilinganiswa ngomphumela we-Doppler.
Amapharamitha obuchwepheshe ayinhloko

Incazelo	Imininingwane
Umthombo wesignali yamandla	Imvamisa yesiginali: 20hz ~ 60 khz Inani eliphansi lesinyathelo: 0.0011 hz Ukunemba kwemvamisa: ± 20ppm I-voltage yokuphuma: 1mv ~ 20vp-p Impedance 50 ohm
