The ugboro ole nso na Radio na Television

Frequency iche - a okwu nke na ọtụtụ-eji na N'ezie nke ahụ oru na-achị, akpan akpan ke ngwá electronic. N'okpuru a echiche na ọ na-aghọta dị ka na-arụ ọrụ dịgasị iche iche nke a na ngwaọrụ na a raara onwe ya nye radio ọrụ n'ihi akpọsa a akpan akpan ugboro nso. Na anyị nwere ike ikwu banyere mmebi nke niile na redio ugboro nso.

International iwu nditịm mezie ojiji nke dị iche iche radio na agbasa ozi n'ikuku na usoro (gụnyere satellite), a na-kọwaa nso. Nke a na-tụziri nke mkpa iji hụ interoperability nke dị iche iche na usoro na-arụ ọrụ iji kpochapụ nnyonye anya.

Dị ka Radio Regulations, n'ógbè nke Earth ekewa atọ nnukwu district. The mbụ na-agụnye Europe, CIS, Russia, Mongolia na Africa. The abụọ - ókèala America (ma North na South). Nke atọ - South na South-East Asia, Australia, na Pacific mpaghara. Na nke ọ bụla ebe - ya nkesa radio ugboro gbalaga.

Maka ọrụ satellite nkwurịta okwu iwu na-enye ugboro ìgwè na akara: L, S, C, X, Ku, Ka, K àmà site 1452 MHz ka 86,0 GHz. Ihe ka nnọọ ọtụtụ nke satellite usoro ọrụ na ìgwè C na Ku. Nso Ka ifịk ifịk mepụtara na Europe na America, ma ná mba anyị na-adịghị ọtụtụ mee.

The mpi arụmọrụ bụ dabere na ọnụ ọgụgụ nke wavelengths na dabara na dayameta nke mpi. Na-amụba ugboro ole, ndị wavelength na- ebelata (ndị a ụkpụrụ na-inversely proportional) na nnukwu mpi adịghị chọrọ na-enweta elu ugboro n'ókè. Ebe ọ bụ na ugboro ole nso natara site poolu size of 2.5-4.5 mita, na ka a na-chọrọ ife gbalaga K poolu size -. Naanị 10-15 cm na otu size antennas arụ ọrụ na elu nso, nwere elu uru.

Na nke ọ bụla akpọsa transmitter ojii na-nwere ya ugboro nso. E nwere a nhazi ọkwa nke radio mmiri na ebili mmiri na nso na wavelength. Dị ka nke a-efegharị efegharị na-:

- Dekametricheskie na a wavelength nke iji nke 10 000-100 000 kilomita, onye frequencies na-nkewa dị ka oké ala (3 - 30 Hz).

- Megametricheskie (wavelength - 000 kilomita 1000-10), ugboro nso - 300 Hz.

- Gektokilometrovye (na a ogologo 100-1,000 kilomita) metụtara ultralow ugboro (3000 Hz).

- Extra ogologo (ogologo - 10-100 kilomita) - nnọọ ala (ruo 30 kHz).

- ogologo (ogologo nke 1-10 kilomita) - ala (ruo 300 kHz).

- Nkezi (ogologo 100-1000 mita) - mids na 3000 kHz.

- Short, na-enwe ogologo nke 10-100 mita - ọ bụ na-akpọ .. elu ugboro (ugboro 30 MHz).

- Ultrashort ma ọ bụ mita (ogologo 1-10 mita), dị nnọọ elu (ruo 300 MHz).

- Decimeter (ogologo 10-100 cm) na àjà ihe ọṅụṅụ-elu, ruo 3000 MHz.

- sentimita (1-10 sentimita n'ogologo), ibu-elu (ruo 30 GHz).

- millimeter (ogologo 1-10 mm), dị nnọọ elu (ruo 300 GHz).

300-3000 GHz ugboro nso na-ezo aka t. N. hyper-elu ugboro nso.

Na mbụ nkebi nke mmepe nke radio mmiri na ebili mmiri na-eji ukwuu n'ime ogologo na ibu-ogologo nso. Ma ha na-agbasa n'elu ụwa elu, na-ike etinye obi gị dum, chọrọ ike transmitters. Anụ oriri a rụrụ na-ajụ ife, ma ha na ọ bụ ike iji hụ na nnyefe anya, na-eji a nso, ukwuu n'ime obodo redio na a na okirikiri nke ọtụtụ narị kilomita.
