Zviratidzo zvekubvuma zvinogona kukamurwa kuitazviratidzo zvesimbauyezviratidzo zvesimbamaererano nesimba ravo. Masaini emagetsi anogona kukamurwa kuita masaini eperiodic uye aperiodic masaini zvichienderana nekuti ari periodic here kana kwete. Chiratidzo chesimba chine magumo muamplitude uye nguva, simba rayo rinopera, uye simba rayo repakati (pamusoro penguva isingaperi) i zero. Nguva yechiratidzo chesimba haiperi, saka simba rayo hariperi.
Zvimiro zvechimwe chiratidzo zvinogona kudzidzwa mune zvese frequency domain uye iyo nguva domain.
Panemarudzi mana echiratidzozvivakwa mu frequency domain: spectrum, spectral density, simba spectral density uye simba spectral density. Iko waveform ye periodic simba chiratidzo inogona kumiririrwa neFourier series, uye zvinhu zvezvikamu zvinoumba discrete spectrum yechiratidzo, uye chikwata chayo chinonzi V. The waveform yechiratidzo chesimba inogona kumiririrwa neFourier shanduko, uye basa rinowanikwa neiyo waveform shanduko ndeye Kupenya density yechiratidzo, iyo unit ndeye V/Hz. Chero bedzi iyo impulse function yakaunzwa, isu tinogona zvakare kuwana yayo spectral density yechiratidzo chesimba. Iyo simba spectral density ndiko kugoverwa kwesimba rechiratidzo chesimba mune frequency domain, uye unit yayo iJ/Hz. Iyo simba spectral density ndiko kugoverwa kwesimba rechiratidzo chesimba mune frequency domain, uye unit yayo iW/Hz.
Zvinozivikanwa kutimaitiro echiratidzomudura renguva rinonyanya kusanganisira iyo autocorrelation basa uye muchinjika-yekubatanidza basa. Basa re autocorrelation rinoratidza chiyero chekubatana pakati pehutano hwechiratidzo panguva dzakasiyana. Iyo autocorrelation basa R (0) yechiratidzo chesimba yakaenzana nesimba rechiratidzo; uye iyo autocorrelation basa R (0) yechiratidzo chesimba yakaenzana neavhareji simba rechiratidzo. Basa remuchinjiko rinoratidza chiyero chekubatana pakati pezvikwangwani zviviri, izvo zvakasununguka pane nguva uye zvine chekuita chete nemusiyano wenguva, uye basa remuchinjiko rinoenderana nekurongeka kwezviratidziro zviviri. Iyo autocorrelation basa rechiratidzo chesimba uye simba rayo spectral density inoumba mbiri yeFourier inoshandura. Iyo autocorrelation basa reiyo periodic simba chiratidzo uye simba rayo spectral density inoumba mbiri yeFourier anoshandura. Iyo muchinjika-yekubatanidza basa rechiratidzo chesimba uye muchinjika-simba spectral density inoumba mbiri yeFourier inoshandura. Iyo periodic simba chiratidzo chemuchinjiko-yekubatanidza mashandiro uye ayo muchinjiko-simba spectrum inoita mbiri yeFourier inoshandura.
Chiratidzo chakasimbiswa chinenge chiri pamusoro chipfupi sumo. Ndinovimba chinyorwa ichi chinogona kukubatsira iwe kuwedzera ruzivo rwako. Kunze kwechinyorwa ichi kana iwe uchitsvaga yakanaka optical fiber yekutaurirana michina yekugadzira kambani yaungafunganezvedu.
Shenzhen HDV photoelectric Technology Co., Ltd. inonyanya kugadzira zvigadzirwa zvekutaurirana. Parizvino, midziyo inogadzirwa inovhara iyoONU series, Optical module series, OLT series,uyetransceiver series. Isu tinogona kupa masevhisi akagadziridzwa kune akasiyana mamiriro. Unogamuchirwaconsult.
