Frequency kutsauka

Frequency - ndiwo mumwe zvechadenga amplitude pakati oscillations chaiyo yakawanda panyaya ayo kunoreva ukoshi. In wefizikisi, kune marudzi akawanda vibrations akasiyana hunhu, somuenzaniso, nokufamba mukati remagetsi mumunda. Kuwedzera kwatangwa remagetsi Mafungu rwokuzvarwa mavambo, pane nokufamba, panowanikwa unopirwa nokuda murume kugadzirisa chaizvo matambudziko kunobva zvinodiwa nemabasa evanhu. Kakawanda achishandisa oscillatory pezvakaitwa kugadzirisa nyaya simba kuchinjirwa uye / kana ruzivo, kureva Zviri pakukurukurirana, redhiyo, terevhizheni uye basa, etc.

Muitiro achitumira mashoko inosanganisira kwegadziriro runoenzanirana simba munda wayo vachisiyanisa inzwi pakati anobatsira chiratidzo uye ari generating wokutepfenyurisa inotakura kakawanda yakajeka parameter tsika - amplitude uye maitikiro. Chokutanga parameter ndiyo Proportional kune simba munda, uye anosarudza nokupfuuridzirwa kure, uye wechipiri - the addressee. Panguva iyi tine inotakura chiratidzo chete, kuita basa "keriya" mashoko.

Mashoko zviri simba munda chakaunzwa chiratidzo pedyo runoenzanirana nokuchinja chero parameters ayo. In tsika, kushandisa mikana siyana yokugadziridza munda parameters - uye izvi zvinonzi vachisiyanisa inzwi keriya maitikiro. Panyaya iyi, kuchinja rinoshandiswa inotakura, kana amplitude uyo akaendesa Frequency kutsauka. Panguva padariro kuva redhiyo anowanzoshandiswa amplitude vachisiyanisa inzwi, apo mashoko ari huri amplitude uyo akaendesa chiratidzo. The kuchinja keriya amplitude zvakarurama
Information akadzokorora analoginen chiratidzo. Mutengi anogamuchira chiratidzo
hwaro mutakuri kakawanda, uye ipapo allocates demodulator zviri mukati
ruzivo. Yakaderera frequencies, kusvikira pfupi-wave zvenguva, achishandisa chete amplitude vachisiyanisa inzwi. chikuru chinetso Its ndiye Kuchinja amplitude uyo akaendesa kakawanda, nokuda izvo chiratidzo - ruzha reshiyo, unokosha chokukomborerwa kunaka kukurukurirana chiteshi ipfupi.

Uyewo ari amplitude vachisiyanisa inzwi, kuparadzira mashoko akashandiswa uye kakawanda panguva iyo kakawanda kutsauka inoshandiswa. Kunakisa maitikiro
Kusiyanisa inzwi - yepamusoro ruzha kutapata, saka basa
Communications hurongwa anoshandiswa chete chastotnomodulirovannye anonongedzera. Muenzaniso kushanda anonongedzera dzakadaro - VHF redhiyo, terevhizheni, inokosha kukurukurirana.

Kutsauka - kufadza akaendesa kakawanda shanduko hama kuti avhareji kukosha kwayo. The chakarondedzera kakawanda-modulated keriya oscillation kunoenderana amplitude ari anobatsira chiratidzo chacho amplitude hazvirevi siyana, apo kubatana kutsiga kwakakwirira zvikuru kupfuura pakutanga.

mutakuri kakawanda kuti kakawanda vachisiyanisa inzwi mano dzinonzi modulators chiratidzo. basa ravo nokupfuuridzirwa redhiyo anonongedzera - the jenareta kudzora akaendesa wokutepfenyurisa maitikiro. Anosarudza kakawanda kutsauka
zvinodiwa kuti noupamhi pamusoro bandwidth zvose wokutepfenyurisa uye receiver.

Sezvo mukuru chinodiwa kuti aakaudzwa mugero - zvichida yakarurama kwemashoko yepakutanga chiratidzo, kuti bandwidth pakati mazano-goho mumatunhu ari mugamuchiri uye wokutepfenyurisa zvinofanira kanenge kaviri kukosha yepakutanga chiratidzo bandwidth. Zvisinei, pano tine kutsvaka "yendarama Zvichakadaro", nekuti hazviiti kutsauka kudivi wokutepfenyurisa inogona chokuita parasitic oscillations anokonzerwa extraneous nemwaranzi zvose pickups, uye pakasikwa kukanganiswa nemaune, sezvo nzira imwe pakubata kukanganisa chiratidzo kwakadaro - varambidzwe kudya of bandwidth. Kazhinji vanotaura ukama pakati huru
Kutsauka zvatariswa - uye kuzununguka boka upamhi chakarondedzera chiratidzo zvitange.

Kana vachisiyanisa inzwi maindex kukosha kwazvo, zvose parameters, izvo
dzinoratidzwa kakawanda kutsauka, vane ndezvomuzana zvakafanana zvikuru. The kutsaudzira akayera mu vamapoka Frequency Hz.
