Ukwethulwa komkhiqizo omusha - i-audio frequency sweep signal generator

Uchungechunge olusha lwe-rk1212 kanye nochungechunge lwe-rk1316 amajeneretha ezimpawu zokushanela imvamisa yomsindo athuthukisa ukusebenza ngesisekelo semikhiqizo yasekuqaleni futhi abe nokusebenza kwezindleko eziphakeme.Umkhiqizo omusha wamukela ukulawula kwe-MCU, futhi isignali yokuphumayo izinzile;Ukubukeka kwensimbi kuyathuthukiswa, futhi ukhiye wokusebenza we-silicone usetshenziselwa ukuthuthukisa impilo yesevisi yensimbi;Ukulebula okunembe kwenkomba, njengokulungiswa kwemvamisa, kuhlukile kwezinye izinkomba ezingamanga.Uchungechunge lwe-Rk1316 alunazo zonke izinzuzo zochungechunge lwe-rk1212 kuphela, kodwa futhi lunomsebenzi wokuhlola i-polarity, ngakho-ke asikho isidingo sokuyithenga ngokwehlukana;Iphinde ibe nesipikha sayo kanye ne-earphone, futhi ingashintsha i-voltage ngokukhululeka.Lolu chungechunge lwamathuluzi lunezici ezilandelayo:

1. Ubuchwepheshe be-Direct digital synthesis (DDS) bamukelwa;

2. Imvamisa yokuphuma kwe-waveform ingu-20Hz ~ 20kHz, futhi isilinganiso sokushanela sifika ku-1000;

3. Ukulungiswa kwefrikhwensi kungu-1 Hz;

4. Ukuqina kwemvamisa ≤ 5 × (10);

5. I-amplitude ephumayo yesiginali encane ingu-10mvrms;

6. Imvamisa yokuqala kanye nemvamisa yokuphela yokuskena ingasethwa ngokungafanele;

7. Inamandla ekukhiqizweni kokulibaziseka kanye nomsebenzi wokuvikela umkhawulo wamanje wesifunda esifushane;

8. Uchungechunge lwe-Rk1316 olunomsebenzi wokuhlola i-polarity, asikho isidingo sokuthenga ngokwehlukana;

9. Uchungechunge lwe-Rk1316 lunesipikha salo kanye ne-earphone, futhi lungashintsha ugesi ngokukhululeka.
