Pretsizion attenyuator
|
Attenyuator (so‘ndirgich) kuchlanishni talab qilingan marta susaytirish uchun xizmat qiladi. Asosan yuqori chastota o’lchov apparatlarida, masalan, standart signallar generatorlari va komparatorlarda qo‘llaniladi.

yunon. di... ikki martalikni bildiruvchi old qo’shimcha va еlektr od) – bir tomonlama еlektr o’tkazuvchanlik xossasiga еga bo’lgan ikki еlektrodi asbob. Еlektrvakuumli, yarim o’tkazgichli diod, gazotron xillari bor. Radiotexnika, еlektronika, еnetgetika va texnikaning boshqa sohalarida asosan, o’zgaruvchan tokni to’g’rilash, detektrlash, chastotani qayta o’zgartirish, еlektr zanjirlarni almashlab ulashda ishlatiladi.

Greek. di... prefix denoting duality and electric od) is a two-electrode device with the property of one-way electrical conductivity. There are types of electric vacuum, semiconductor diode, gasotron. In radio engineering, electronics, energy engineering and other fields of technology, it is mainly used for alternating current rectification, detection, frequency conversion, alternating connection of electric circuits.

(lotincha: compare — taqqoslayman) — 1) fizik kattaliklarning oʻlchamlarini mos etalon (namuna) oʻlchamlariga solishtirib aniqlaydigan oʻlchash asbobi (teng yelkali tarozilar, elektr-oʻlchash potensiometrlari va boshqa taqqoslash asboblari); nazorat-oʻlchash vositalaridan biri. Mexaniq (yelkali tarozilar), elektr (oʻlchash koʻprigi), optik (optimetr), interferension (interferometr), stereoskopik va boshqa turlari bor. K. yordamida uzunlik, burchak, massa, bosim, tok kuchi va boshqa oʻlchanadi. Haritalar tuzish ishlarida stereokomparatorlar qoʻllanadi.

(Latin: compare — I compare) — 1) a measuring device that determines the dimensions of physical quantities by comparing them with the dimensions of a suitable standard (sample) (scales with equal shoulders, electro-measuring potentiometers and other comparison devices); one of the control and measurement tools. There are mechanical (shoulder scales), electrical (measuring bridge), optical (optimeter), interference (interferometer), stereoscopic and other types. K. is used to measure length, angle, mass, pressure, current, etc. Stereocomparators are used in mapping.
