Kuyini feedback negative?

Nakuba inkulumo ethi "impendulo engeyinhle" akwaziwa kuwo wonke umuntu, inqubo ngemuva kwaso, ebhekene wonke umuntu nsuku zonke. Omunye kungaba usho nezibonelo eziningi. Futhi, kuyathakazelisa ukuthi le impendulo engeyinhle asitholakali eziphilayo, kodwa nezalo izinsiza eziningi lobuchwepheshe. Ngokwengxenye, kuphela ngenxa intuthuko yakhe kukhona endleleni lapho thina zijwayele.

Isimiso lwempendulo sifundwa kuwo amagatsha ezihlukahlukene isayensi. Ngokwesibonelo, e umculo ikhono lokusebenzisa impendulo (impendulo), ikakhulukazi ezinye odumile rock abaculi ezifana Kurt Kobeyn, Xhumanisa Ray nabanye. It ifundiswa biology, omakhenikha, ubunjiniyela kagesi, electronics ... Eqinisweni, yonke indawo. Ngenxa yalokho, umuntu kalula thola eziningi izimpendulo ezahlukene yombuzo "liyini impendulo engeyinhle" e inethiwekhi global, kodwa ngokuvamile izimpendulo ngokwabo okwengeziwe zisenza sibe imibuzo emisha. Konke lokhu naphezu kweqiniso lokuthi injongo impendulo ezinzima elula.

Kuyini feedback negative? Nazi izibonelo ezimbalwa ekuphileni. Cabanga umuntu uhamba ezindaweni ezishelelayo. Lapha uthatha isinyathelo esisodwa, kuba ngolunye, futhi enye ... bese umlenze iqala kushelela, isikhungo umzimba ye-gravity kancane kancane (nje sengathi kweso) usekhuluma - kunengozi yangempela falling. Kuleli qophelo, amaqembu athile imisipha ziyancipha, efuna ezinye indlela isinxephezelo esingamanga kahle. Lokhu ukuphambuka kungaba emuva noma, kunalokho, ezinye izinyathelo phambili e zezindlu esitshekile. Nokho, kuleli cala, thina ukuchaza kuphela ukubonakaliswa kwangaphandle. Mshini yangaphakathi isebenza ngale ndlela:

• ngezinyawo iba ngaphezulu. Kuleli qophelo kuwo zithunyelwa amasignali ubuchopho kubonisa amandla (ngamunye ngaphandle kokungabaza ukunquma esithambile noma isizinda kanzima), maholoholo, emthambekeni;
• ngokuhambisana idatha wathola eqondiswa isikhundla umzimba kanye nokubekwa izinyawo;
• kodwa unyawo waqala kushelela. ukuzinza usongo. I bazolokhu ukushelela, kulapho ngenkuthalo efuna kanye nokuqaliswa indlela engcono kungavimbela ekwindla.

okubuyayo usetshenziswa skier, elibuye Nyakazisa umzimba, okwandisa ukushelela velocity. Ngakwelinye ihlangothi, inhlangano negative umelana izimbangela izinguquko ohlelweni.

By endleleni, abadlali abaningi okuyiqondisa ngempendulo ezaziwayo. Lona-ke! Kunamandla umdlali uphendukela amasondo ayo nganxanye, ukumelana ngaphezulu kusukela motor yangaphakathi azizwa. Kulesi sibonelo, kukhona zamanje impendulo.

Schematically, kubukeka sengathi lokhu: okokufaka - uhlelo - okukhiphayo. Uma noma iluphi ushintsho idatha input bese ushintsho esifanele okukhiphayo. Lesi sakamuva, ngesikhathi esifanayo, ngaleyo ndlela nomthelela ohlelweni uyibuyisele isimo sokuqala esitebeleni.

Impendulo yokukhulisa umsindo ongaxazulula izinkinga eziningana ngesikhathi esisodwa: ukuqinisekisa ukuzinza inzuzo kungakhathaliseki isignali okufakwayo, okwenza wonke uhlelo okuzenzakalelayo ngokugcwele (impendulo Tuning wenziwa kuphela lapho besanda kuqala). Nokho, impendulo engeyinhle akubangelwa njalo ukuthi electronics elula. I engavamile itholakala lokuthi ukuthi isiginali impendulo eza ohlelweni, kufanele abe nesikhathi kusebenze izindlela compensatory ngaphambi kabusha okokufaka ushintsho idatha. Ngamanye amazwi, ijubane impendulo kufanele idlule izinga izinguquko isignali okufakwayo. Ngakho-ke, uma isikimu esekelwe microwave amaza, eziningana nobunzima. Omunye isixazululo - Imvamisa yokuvumelanisa idatha input bese impendulo.
