Mune zvemagetsi, kubatanidzwa kwehunyanzvi hwepamusoro uye dhizaini inoshanda yakakosha.Vaviri vakakosha vanobatsira pandima iyi pulse code modulation (PCM) uye akadhindwa edunhu mabhodhi (PCB).PCM nePCB zvinoshandiswa zvakanyanya mumhando dzakasiyana dzemagetsi, uye chimwe nechimwe chine zvachakanakira uye maitiro.Mune ino blog, tichaparadzanisa mutsauko uye kugona kwePCMs nemaPCB kuti tione kuti ndeipi sarudzo iri nani pane zvaunoda.
PCM (Pulse Code Modulation):
Pulse Code Modulation inzira yedhijitari yekumiririra masaini eanalog.Iyo inoshandura masaini eanalog kuita dhijitari fomu uye inonyanya kushandiswa mumaodhiyo maapplication akadai sekurekodha uye kugadzira mimhanzi.PCM nguva nenguva inotora amplitude yemuenzaniso wega wega weanalogi chiratidzo uye inomiririra iyo digitally.Iyi sampling tekinoroji inonyatso kuburitsa iyo yekutanga analogi chiratidzo.PCM inopa kujeka kwakanakisa kweruzha uye inozivikanwa nekutendeseka kwayo kwepamusoro, zvichiita kuti ive yakakodzera kugadzira maodhiyo masisitimu nemidziyo inoda isingachinjiki ruzha rwemhando.
PCB (Yakadhindwa Circuit Board):
Mabhodhi edunhu akadhindwa ndiwo hwaro hwepanyama hwemidziyo yemagetsi, ichipa chikuva chekubatanidza kwezvikamu zvakasiyana.A PCB ine nzira dzinofambisa dzakaiswa mune isiri-conductive substrate kuti ipe magetsi ekubatanidza uye mechanical rutsigiro rwezvikamu.MaPCB anofambisa kurongeka uye kubatana kwezvinhu zvakasiyana-siyana zvemagetsi senge resistors, capacitors uye microchips.Iko kuchinjika kwePCB dhizaini inobvumira kurongeka kwakaoma kwedunhu, ichiita kuti ishandiswe zvakanyanya mumaindasitiri akasiyana akadai seyekufonera, aerospace, uye zvemagetsi zvevatengi.
Zvinhu zvinosiyanisa:
1. Basa:
PCM inonyanya kutarisisa padhijitari odhiyo chiratidzo chekugadzirisa kuti ipe yemhando yepamusoro kubereka kwekurira.Kune rimwe divi, maPCB anobatsira mukushanda kwese kwemagetsi emagetsi, kufambisa kubatanidzwa kwezvikamu zvakasiyana uye kupa kugadzikana kune sisitimu.Nepo maPCM ari chikamu chakakosha cheodhiyo masisitimu, maPCB anoshandiswa mune angangoita ese emagetsi mudziyo, kubva kumafoni kusvika kune zvekurapa.
2. Dhizaini yakaoma:
PCM inonyanya kusanganisira software algorithms uye epamberi masaini ekugadzirisa maitiro.Kunyangwe ichida hunyanzvi muinjiniya yekuteerera uye hunyanzvi hwekugadzirisa hunyanzvi hwekuita kuti iwedzere kuita kwayo, iri nyore maererano nekugadzirwa kwemuviri.Mukupesana, PCB dhizaini inoda kungwarira marongero, kuiswa kwechikamu, uye kuongororwa kwekubatanidza magetsi.Zvinoda ruzivo rweinjiniya yemagetsi uye maitiro ekugadzira anoshanda kuti awane basa rinodiwa.
3. Kusiyana-siyana:
PCM yakanyatsogadzirirwa maodhiyo ekushandisa kuti ive nechokwadi chekumiririra ruzha uye kuderedza kukanganisa.Chinangwa chayo chikuru kuchengetedza kutendeseka kwechiratidzo chekuteerera mudhijitari domain.Kune rimwe divi, maPCB haana kuganhurirwa kune chero application kana indasitiri.Kushanda kwavo kwakasiyana-siyana kunobvumira kuti vagadziriswe kuti vaenderane nezvinodiwa zvechero mudziyo wemagetsi, ingave inotakurika mimhanzi inoridza kana setiraiti yekutaurirana system.
mukupedzisa:
Ose maPCM uye maPCB akakosha anobatsira kumunda wemagetsi, imwe neimwe ichishandira chinangwa chakasiyana.PCM ndiyo yekutanga sarudzo yeinjiniya yekurira uye audiophiles yemhando yepamusoro yekuteerera.PCBs ndiyo hwaro pakavakirwa yakaoma emagetsi masisitimu, kuve nechokwadi chekubatana uye kugadzikana.Kunyange zvazvo maPCM nePCB akasiyana mukushanda uye kugadzira, anowanzoshandiswa pamwe chete mumagetsi emagetsi, achibatanidza masimba avo akasiyana.
Pakupedzisira, zvinouya kune izvo zvinodiwa zvepurojekiti yako kana michina.Kunzwisisa mutsauko uye hunhu hwePCM nePCBs zvinokugonesa iwe kuita sarudzo ine ruzivo zvichienderana nezvaunoda.Saka kunyangwe uri kuvaka hi-fi system kana kugadzira multifunctional electronic equipment, maPCM nePCBs maturusi akakosha ekusimudzira tekinoroji.
