Usavhiringidze iyo wave generator nemimwe michina yatakatoona mune ino blog uye inogona kutaridzika zvakafanana, senge oscilloscopes. Muchinyorwa chino tichadzidza kuti wave jenareta chii, chaungashandise mumapurojekiti edu emagetsi, maitiro ekusarudza akanakisa, nezvimwe.
Uyezve, ini ndicharatidzawo zvimwe zve akanakisa wave jenareta izvo zvatinokurudzira, kuitira kuti iwe ugone kutenga michina inoenderana nezvido zvako…
Iwo akanakisa wave jenareta
Kuwana akanakisa wave jenareta, tinokurudzira zvishandiso zvinotevera zverabhoritari yako yemagetsi:

Chii chinonzi wave jenareta kana chiratidzo jenareta?
Un wave jenareta, kana chiratidzo jenareta, Icho chishandiso chinoshandiswa kunyanya munzvimbo dzemaindasitiri chinoburitsa chiratidzo chemagetsi muchimiro chesaisai chinogona kuunzwa mudunhu remagetsi kuita mhando dzakasiyana dzebvunzo pamwe nemamwe maindasitiri ebvunzo uye kuyerwa zviridzwa. Kureva kuti, nepo masaini kubva kudunhu achiyerwa muoscilloscope, mujenareta anopinzwa mudunhu...
Iyo jenareta yechiratidzo inogona kugadzira inodzokorora waveforms ne zvimiro zvakajairika senge sikweya, pulse, sinusoidal, triangular, sawtooth, pakati pezvimwe. Iyo ine application muhuwandu hweminda, kwete zvemagetsi chete, asiwo mune zvemagetsi zvikumbiro.
Zvakakosha kuziva kuti wave generator Haina basa rekuyera chiratidzo chainoburitsa, kunyange zvazvo uchigona kuzviratidzira. Basa rayo guru nderekuisa simba kana kuyedza maseketi emagetsi kana ma actuators munzvimbo dzemaindasitiri, kana marabhoritari emagetsi, mukusimudzira uye mukusimbisa mashandiro avo.
Sezvandambotaura, wave jenareta anoshandiswa kugadzira zviratidzo zve periodic, umo magetsi anosiyana nguva nenguva nekufamba kwenguva, achibvumira nguva yaro (nguva ye oscillation yakakwana) uye amplitude yayo (yakawanda kukosha kwechiratidzo chemagetsi) kuti idzorwe. Nekudaro, inogona zvakare kuita basa rakakosha mukugadzirwa kwemasaisai asiri enguva.
Inonyanya kushandiswa mukati kugadzira, kuedza uye kugadzirisa yezvigadzirwa zvemagetsi. Uye zvakare, inogona zvakare kuve nehunyanzvi maapplication uye kushandiswa munharaunda yekurapa. Mazuva ano, nekuda kwekuenderera mberi kwe tekinoroji, kune chaiwo majenareta ezviratidzo zvemabasa akasiyana siyana. Midziyo iyi inogona kubatirwa zvakananga mumakomputa uye inopa mabasa akadai sekutema masaini anogadzirwa uye kugona kuronga jenareta kuti ibudise yakatarwa kutevedzana kwezviratidzo.
Chii chinonzi wave generator chinoshandiswa?
ari common applications Wave jenareta akakamurwa mumapoka akati wandei, kusanganisira:
- Maintenance uye sevhisi yezvigadzirwa zveindasitiri: Ivo vanoshandiswa kuita bvunzo uye kuongororwa pamidziyo yemaindasitiri, kuve nechokwadi chekushanda kwayo kwakaringana.
- Tsvagiridzo nedzidzo: Iwo maturusi akakosha muzvirongwa zvekutsvagisa uye marongero edzidzo, kwaanoshandiswa pakuedza uye kuratidzwa.
- Shandisa mumunda kana munzvimbo dzakachengeteka: Masignal jenareta anotakurika uye anoshandiswa mumunda kana munzvimbo dzinodiwa kuchengetedza, sekuyedza munzvimbo dzakadzorwa.
- Kugadzirwa kuri nyore: Iwo zvakare anoshandiswa mune akareruka ekugadzira zvikumbiro uko masaini chaiwo anoda kugadzirwa kuti ayedze uye kuenzanisa.
En mazwi ekushandisa uye akajairika mabasa yewave jenareta inogona kupfupikiswa mumapoka matatu makuru:
- Kugadzira masaini: Midziyo iyi inogona kugadzira masaini kubva kutanga kutevedzera, kumutsa uye kuyedza akasiyana maseketi uye zvishandiso.
- Signal replication: Vanogona kudzokorora masaini, angave anomalies, zvikanganiso kana masaini akawanikwa neoscilloscopes, murabhoritari kuti agadzirise maparamita avo uye aaongorore munzvimbo inodzorwa.
- Chigadzirwa chechiratidzo: Iwo anoshandiswa kugadzira masaini akakodzera kana anozivikanwa mabasa anoshanda sereferensi kana yekuisa yekuyedzwa.
Uyezve, majenareta echiratidzo ane zvakakosha maapplication mukati wireless telecommunication indasitiri uye aerospace indasitiri, kwavanogona kutevedzera zvikwangwani zvakaita seradar kana GPS, kana kuyedza zvinogamuchira dhijitari uye zvinotapurirana.
Zvakakosha, majenareta emagetsi anoita basa rakasiyana kana richienzaniswa nemamwe maindasitiri ebvunzo uye kuyerwa zviridzwa, senge spectrum analyzers, multimeters uye oscilloscopes. Nepo iyo yekupedzisira chiyero chedhijitari kana analog masaini, jenareta inoburitsa chiratidzo umo mushandisi anosarudza oscillation frequency yewave ...
Misiyano pakati pemajenareta echiratidzo uye majenareta ebasa
Iwe unogona kunge wakashamisika pane imwe nguva kana zviridzwa zviviri izvi zvakafanana kana kana zvine misiyano yakakura, zvakanaka, zvese chimwe nechimwe chine kugona kugadzira chiratidzo iyo inounzwa mudunhu kuti ione maitiro ayo, asi pane akati wandei anocherekedza misiyano.
El Basa jenareta inokwanisa kugadzira mabasa akatemerwa akajairwa, akadai se:
- Sine kana sinusoidal mafungu.
- Square zviratidzo.
- Triangular shapes.
- TTL zviratidzo.
Inonyanya kushandiswa mu kuenzanisa mudziyo nokuda kweaudio, ultrasonic applications uye servo systems, inoshanda muhuwandu hwehuwandu hwe0.2 Hz kusvika 2 MHz. Iyo technician ine kutonga pamusoro pema paramita akadai seDC offset level, scan kutenderera, huwandu uye hupamhi, pamwe nechiratidzo amplitude.
Kunyange zvazvo mune zvimwe zvinhu zvingaratidzika zvakafanana, hazvigoni kurangarirwa zvakafanana zvakafanana. Nekudaro, nekuda kwekufambira mberi mune tekinoroji, majenareta anogona kugadzira masaini akawanda ayo aimbove akabatana chete nejenareta inoshanda, izvo zvakakonzera musanganiswa wepfungwa pakati pemhando mbiri dzezviridzwa.
Mhando dzemagetsi emagetsi
Iwe unofanirwa kuziva izvo zvinogona kuwanikwa pamusika marudzi akasiyana-siyana emagetsi emagetsi kana majenareta emagetsi, ane hunhu chaihwo hunovasiyanisa, asi izvo zvaunofanirawo kuziva:
- Pulse jenareta: Chishandiso ichi chinogona kuburitsa pulses, kusanganisira logic pulses ine kunonoka kwakasiyana uye nhanho shanduko, iyo inobatsira mukuyedzwa kwedhijitari wedunhu, uye dzimwe nguva mukushandisa zvine musoro. Unogona kutumira zvitima zvemapulses kuti uvhure zvikamu zvakati zvedunhu.
- Jenareta redhiyo chiratidzo chechimiro: Yakagadzirirwa mapurojekiti ekuteerera, inoshanda mune frequency renji ye20 Hz kusvika 20 kHz. Mune zvimwe zviitiko, inogona zvakare kushandiswa kugadzira sine mafungu uye mamwe maaudio waveform.
- Arbitrary waveform jenareta: Iyi tekinoroji yepamusoro inobvumira tsika waveforms kugadzirwa uye kugadziridzwa nenzira dzakaoma. Nekudaro, majenareta aya anodhura nekuda kwekuoma kwawo uye anoda kudzikisira bandwidth yavo. Usati watenga imwe, zvakakosha kufunga nezve kushandiswa kwayo.
- RF (Radio Frequency) Chiratidzo Jenareta: Sezvinoratidzwa nezita rayo, inoshanda muredhiyo frequency renji. Inogona kuburitsa modulation mune waveform, senge AM (Amplitude Modulated) kana FM (Frequency Modulated), uye mhando dzepamusoro-soro dzinogona kushanda nematekinoroji akadai seCDMA neOFDM, akajairika munharembozha. Mune zviratidzo zveanalog, vanopa mahara oscillation uye vanogona kushandisa periodic kukiya matekiniki kuvandudza kugadzikana kwechiratidzo.
- Vector chiratidzo jenareta: Aya majenareta akafanana nemajenareta eRF, asi anosiyana mukugona kwavo kushanda nemamwe mafomati akaomarara, akadai seQAM (Quadrature Amplitude Modulation) uye QPSK (Quadrature Phase Shift Keying). Naizvozvo, iwo anoshandiswa kuyedza epamberi telecommunication masisitimu, akadai se4G, 5G, uye mamwe masisitimu akafanana.
- Basa jenareta: Kunyangwe isu takatotaura nezve majenareta emabasa, zvakakosha kuti uasanganise pano sezvo ariwo chikamu chemagetsi majenareta. Midziyo iyi inogona kugadzira akareruka anodzokorodza masaisai, senge sine, sawtooth, triangle, uye square waves. Kunyangwe iwo ekutanga mamodheru aive analog, iwo azvino ari edhijitari, asi anogona kuramba achigadzira masaisai akashandurwa kuita analog. Ivo havafanirwe kushanda nepamusoro-soro nekuda kwerudzi rwemasaisai avanogadzira, kunyangwe paine mhando dzinogona kudaro.
