Momwe mungagwiritsire ntchito oscilloscope pakumvera

Oscilloscope ndi chida chofunikira kwa aliyense amene akufuna kugwira ntchito ndi audio.

Izi zimakupatsani mwayi wowona ma waveform, omwe ndi ofunikira kuti muzindikire ndikuthetsa zovuta zamawu.

Mu positi iyi ya blog, tikambirana momwe mungagwiritsire ntchito oscilloscope pakumvera.

Kodi oscilloscope imachita chiyani?

Oscilloscope ndi chida chamagetsi chomwe chimagwiritsidwa ntchito m'malo osiyanasiyana kuwonetsa chizindikiro chamagetsi. Oscilloscope imawonetsa mawonekedwe amagetsi amagetsi, chifukwa chake imagwiritsidwa ntchito powonera ma audio.

Chidacho chimatembenuza ma sign amagetsi kukhala mafunde ndikuwawonetsa pazithunzi zowonetsera zomwe zili ndi X-axis ndi Y-axis. 

Oscilloscope imalekanitsa phokoso kukhala mphamvu / matalikidwe ndikusintha mphamvu pakapita nthawi.

Ngakhale kuti Y-axis imasonyeza kukula kwa phokoso, kusintha kwamphamvu kwa nthawi kumawonetsedwa pa X-axis. 

Momwe mungalumikizire oscilloscope ku audio?

Nyimbo ndi chitsanzo cha mawu, kutanthauza kuti akhoza kuyezedwa ndi oscilloscope.

Kuti muyese nyimbo kapena mawu ambiri, mufunika oscilloscope, player MP3 kapena wailesi monga gwero lanu la nyimbo, chingwe chaching'ono cha foni, mahedifoni, ndi adaputala ya Y.

Cholinga cha mahedifoni ndikumvetsera nyimbo momwe mumayezera, ndipo mahedifoni ndi njira ina yabwino. 

Gawo loyamba pakulumikiza ndikuyesa zomvera ndi oscilloscope ndikuyatsa chidacho. Tsatirani izi pokhazikitsa ulalo wolowera ku AC (kusintha kwapano). Malizitsani zosinthazo posintha zowongolera zoyimirira kukhala volt imodzi pagawo lililonse ndi liwiro lopingasa kukhala millisecond imodzi pagawo lililonse. 

Kutengera kuchuluka kwa mafunde omwe mukufuna, mutha kusintha liwiro lakusesa nthawi iliyonse.

Kuphatikiza apo, mutha kusintha mawonekedwe a oscilloscope kuti muwonjezere kapena kuchepetsa ma waveform. Kuwongolera voliyumu kwa woyimba nyimbo ndi njira ina yosinthira kukula kwa mafunde.

Ndizofunikira kudziwa kuti adaputala ya "Y" imakupatsirani madoko awiri kuti mulumikize mahedifoni anu ndi chingwe chaching'ono cha foni nthawi imodzi. Kumbukirani kuti osewera nyimbo ambiri amakhala ndi chojambulira chimodzi chokha. 

Tsopano ponyani cholumikizira cha Y mu cholumikizira chomvera nyimbo chanu ndikulumikiza mahedifoni anu padoko limodzi ndi chingwe chaching'ono cha foni kudoko lina. Sewerani nyimbo pachosewerera nyimbo kapena pagalimoto yanu, kapena ikani wayilesi pamalo omwe mukufuna kuti mukhale ndi mawu. Valani zomvera zanu kuti mumvetsere nyimbo.

Kugwirizana ndi oscilloscope 

Kulumikiza oscilloscope kungakhale kovuta. Chitsogozo choyambirira cha oscilloscope chingathandize.

Chingwe chanu chaching'ono cha foni chimakhala ndi malekezero amodzi okha, koma mukufuna kulumikiza zingwe zanu ziwiri za oscilloscope: cholowera ndi chotchingira pansi. 

Mukayang'ana kumapeto kosalumikizidwa kwa chingwe chanu chaching'ono cha foni, chimagawidwa m'magawo atatu okhala ndi mphete zotsekera, nthawi zambiri zakuda.

Gwirizanitsani kafukufuku wa oscilloscope kunsonga ya chingwe chaching'ono cha telefoni, ndi malo ozungulira oscilloscope ku gawo lachitatu, kusiya gawo lapakati losagwiritsidwa ntchito.

Phokoso la phokoso la mawu anu liyenera kuwonetsedwa pazenera la oscilloscope yanu ndi matalikidwe amtundu woyima ndikusintha matalikidwe pakapita nthawi pa oscilloscope yopingasa.

Apanso, mutha kuwona ma waveform pama frequency osiyanasiyana posintha kusesa kwa scope. 

Kodi oscilloscope angayese nyimbo?

Chimodzi mwa zolinga za oscilloscope ndi kuyeza mafunde a phokoso. Chifukwa nyimbo ndi chitsanzo cha mawu, zikhoza kuyezedwa ndi oscilloscope. 

Kodi oscilloscope amagwiritsidwa ntchito pa zomvera?

Timayesa phokoso ndi oscilloscope kuti tiphunzire khalidwe la phokoso. Mukamalankhula ndi maikolofoni, maikolofoni imatembenuza mawuwo kukhala chizindikiro chamagetsi.

Oscilloscope amawonetsa chizindikiro chamagetsi molingana ndi matalikidwe ake komanso pafupipafupi.

Kumveka kwa phokoso kumadalira momwe mafundewo akuyandikirana, ndiko kuti, kuyandikira kwa mafundewo, ndikukwera kwa liwu.

Momwe mungalumikizire oscilloscope ndi amplifier?

Imodzi mwa ntchito zodziwika bwino za oscilloscope ndikuthana ndi amplifier. Izi zikunenedwa, oscilloscope yanu ndi chida chabwino chothandizira kuthetsa amplifier ngati mulibe mawu omveka bwino.

Mutha kuphunzira momwe mamvekedwe amamvekera kuchokera pa amplifier poyang'ana mawonekedwe a mawonekedwe pazenera la oscilloscope. Nthawi zambiri, mafunde akamamveka bwino, amamveka bwino.

Yambani ndikuchotsa mapanelo akumbuyo ndi apamwamba a amplifier. Masulani zomangirazo ndi screwdriver kuti muwonetse poyera bolodi lozungulira ndi malo a chassis ofunikira pothana ndi mavuto.

Zingakhale bwino ngati jenereta ya sine wave idalumikizidwa ndi kutulutsa kwa amplifier, ngakhale izi zimatengera mayeso.

Komabe, mosasamala mtundu wa mayeso, kulumikiza jenereta ya sine waveform ku amplifier sikungawononge amplifier kapena oscilloscope.

Ndi bwino kumangitsa jenereta m’malo momangirira ndi kulitulutsa pafupipafupi.  

Kuthetsa mavuto amplifier kumafuna kuti izigwira ntchito monga momwe zingagwiritsire ntchito bwino.

Ngakhale kuti izi zingatanthauze kulumikiza cholankhulira ku mawu otulutsa, kupewa izi ndizovuta. Kulumikiza cholankhulira kungawononge komanso kuwononga makutu anu.

Popeza panopa kuchokera ku amplifier iyenera kupita kwinakwake, ndi bwino kulumikiza chingwe chofiira chokha cha katundu wamagetsi ku amplifier. Pankhaniyi, katundu wamagetsi amatenga mphamvu yochepetsedwa pamene amplifier ikugwira ntchito bwino.

Lumikizani oscilloscope polumikiza chingwe chapansi ku chassis chokulitsa ndikuyatsa jenereta yogwira ntchito. Khazikitsani oscilloscope kulondolera kulumikizana kwapano (DC) ndikuyika zowongolera zina kukhala ziro. 

Ndikoyenera kudziwa kuti cholinga cholumikiza chingwe chapansi ku chassis pansi ndikuteteza kugwedezeka kwamagetsi panthawi ya ndondomekoyi. 

Yambani kuthetsa vuto la amplifier pogwira kafukufuku wa oscilloscope ku gawo la amplifier yomwe mukufuna kuyesa. Mutha kusintha mawonekedwe pa oscilloscope pogwiritsa ntchito masikelo amagetsi ndi nthawi.

Pakuyesa uku, x-axis imayimira nthawi ndipo y-axis imayimira voliyumu, yomwe imapatsa mphamvu yokhotakhota pamene ikudutsa pa amplifier. 

Yang'anani mbali zolakwika za amplifier poyang'ana pa oscilloscope chophimba cha magawo omwe ali ndi mawonekedwe osagwirizana ndi nsonga zapakatikati. Chigawo chathanzi chidzatulutsa mawonekedwe osasunthika okhazikika. 

Komabe, kuyesa magetsi kumafuna kusintha pang'ono pazikhazikiko. Sinthani oscilloscope kukhala AC-zophatikizidwa kuti muwone mphamvu yamagetsi. Mawonekedwe a mafunde omwe samawoneka ngati akunjenjemera mukasindikiza kafukufuku wa oscilloscope motsutsana ndi thiransifoma yomwe imatulutsa imatha kuwonetsa vuto ndi mafunde oyambira.

Pomaliza

Ndiye muli nazo - momwe mungagwiritsire ntchito oscilloscope pamawu. Potsatira njira zosavuta zomwe zafotokozedwa mu bukhuli, mutha kuyamba kujambula ndikusanthula nyimbo ndi mawu anu. Wodala kugwiritsa ntchito oscilloscope!
