Vazhinji vashandisi vevashandisi vakatanga kushandisa dijitari chiratidzoRunhare, asi mune dzimwe nzvimbo dzisina kuvakwa analog chiratidzo runhare ichiri kushandiswa. Vazhinji vashandisi vanovhiringidza analog masaini nemasaini emidijitari. Saka chii chinonzi analog foni? Ndeipi foni yedhijitari yedhijitari?
Analog foni - runhare runotumira ruzha kuburikidza neAnalog Signals. Magetsi Analog chiratidzo chinonyanya kureva kukwikwidza uye kuenderana kuenderera kwechiratidzo chemagetsi, ichi chiratidzo chinogona kunge chiri chidhiru chekushanda zvakasiyana siyana, kuwedzera, kuwedzera, kuwanda uye nekudaro. Analog masaini aripo kwese-kwese mune zvakasikwa, sekuchinja kwezuva nezuva.
Chikwangwani chedijitari chinomiririrwa yedhijitari yenguva yenguva (inomiririrwa neyekutevedzana kwe1 ne 0), kazhinji inowanikwa kubva kuAnalog chiratidzo.
Zvakanakira uye Zvakashata zveMadhigiril Signals:
1, kutora chikamu chakawandisa Nekuti mutsara unoburitsa chiratidzo chechiputi, kutapurirana kwedhijitariIzwi rezwiInoda kuAkisikopo ye20k-64khz bandwidth, uye iyo Analog Yourning nzira inongogara 4khz bandwidth, ndiko kuti, iyo PCM Signal maakaunzi nzira dzinoverengeka dzeAnalog. Kune imwe chiteshi, chiyero chayo chekushandisa chinoderedzwa, kana izvo zvinodiwa kuti tambo yakawedzerwa.
2, izvo zvinodiwa nehunyanzvi zvakaoma, kunyanya tekinoroji yekufananidza inoda kunyorwa kwakanyanya. Kunyatsonzwisisa zvinoreva kuti mutumende, anogamuchira anofanirwa kusiyanisa chinhu chega chega chekodhi, uye chinoita kuti chigadzikiso chebunako, kana dambudziko redhijitari, dambudziko rekufananidzira richava rakaoma kugadzirisa.
3, Iyo Analog / Dhijitari Kutendeuka kuchaunza kukanganisa kwekukosha. Nekushandiswa kweakakura-nhanho dzakabatanidzwa dzakatenderedza uye nekuzivikanwa kwekutapurirana neyenziza
