Yog tias koj txuas koj tus hais lus rau lub suab txuas yam koj tsis paub txog, koj tuaj yeem ntsuas nws cov peev xwm siab tshaj plaws. Koj tseem yuav xav tau qhov no los kho thiab kho koj lub suab txuas ntxiv mus tom ntej.
Tsim nyog
- - oscilloscope;
- - multimeter;
- - amplifier.
Cov Lus Qhia
Kauj ruam 1
Txuas ib qho ntawm cov channel ntawm koj lub suab txuas ntxiv rau tus hais lus, yog tias lub zog ntsuas ntawm tus neeg hais lus pom tseeb siab dua, lossis rau ib qho kev sib npaug, qhov kev cuam tshuam sib luag rau lub impedance ntawm tus ntuav lus. Siv lub resistor ntawm cov hom PEV ua qhov sib npaug ntawm kev thauj khoom, muaj peev txheej ntawm 10 txog 100 watts. Thov siv qhov teeb meem sinusoidal rau cov lus amplifier, qhov zaus uas tuaj yeem yog ntawm 100 txog 200 hertz; koj tuaj yeem xa cov cim suab paj nruag li qub. Nce qhov ntim tsawg dua.
Kauj ruam 2
Lub sijhawm no, saib xyuas lub vijtsam oscilloscope thiab ceeb toom ntawm qhov twg voltage lub teeb liab ua kom dav ntxiv ntawm cov zis amplifier yuav pib. Thaum ntsuas cov txiaj ntsig siab tshaj plaws tawm, tsis txhob nkag siab qhov ntsuas qhov siab ntawm ib qho oscillator mus rau lub tswv yim ntawm cov amplifier uas txuas nrog rau ntau tus neeg hais lus. Qhov no tuaj yeem cuam tshuam cov neeg hais lus.
Kauj ruam 3
Saib cov oscillogram. Daim duab no - https://oldoctober.com/pics/sonics/power01.png
Kauj ruam 4
Hloov qhov txiaj ntsig no hauv cov qauv P = (U x U): (2 x R), qhov twg P yog qhov tso zis hluav taws xob ntawm cov amplifier hauv Watts, U yog qhov tso tawm hluav taws xob ntawm cov amplifier hauv Volts, thiab R yog qhov ua haujlwm load. Txoj kev no koj tuaj yeem suav lub zog ntawm cov amplifier.
Kauj ruam 5
Siv lub ntsuas hluav taws xob ntsuas qhov ntsuas lub zog. Txuas nws nrog diode thiab lub zog. Siv daim duab qauv no los txuas rau - https://oldoctober.com/pics/sonics/power04.png. Siv software qis zaus hluav taws xob ua kom tau txais cov teeb meem sinusoidal.
Kauj Ruam 6
Ua raws li cov ntawv txuas https://iurii-shalaev.narod.ru/download.html#generator thiab rub tawm daim ntawv thov Cov Zaus Siv Hluav Taws Xob tsawg kawg los ntawm lub xaib. Khiav qhov kev pab cuam, txuas rau lub Circuit Court thiab siv lub teeb liab mus rau ntawm lub zog loj. Tom ntej no, siv lub voltmeter los ntsuas lub zog ntawm cov amplifier.
