Antena inokwanisa kutumira kana kugamuchira mafungu emagetsi (EM). Mienzaniso yemafungu aya emagetsi anosanganisira chiedza chinobva kuzuva, uye mafungu anogamuchirwa nefoni yako. Maziso ako ari kugamuchira maantenna anoona mafungu emagetsi pafrequency yakatarwa. "Unoona mavara (tsvuku, girini, bhuruu) mumafungu ese. Tsvuku nebhuruu kungori mafrequency akasiyana emafungu ayo maziso ako anogona kuona.
Mafungu ese emagetsi anopararira mumhepo kana muchadenga nekumhanya kwakafanana. Kumhanya uku kunosvika mamiriyoni mazana matanhatu nemakumi manomwe nerimwe emadhora paawa (makiromita bhiriyoni imwe paawa). Kumhanya uku kunonzi kumhanya kwechiedza. Kumhanya uku kunokurumidza kanenge miriyoni kupfuura kumhanya kwemafungu eruzha. Kumhanya kwechiedza kwaizonyorwa muchiyero che "C". Tichayera kureba kwenguva mumamita, mumasekonzi, uye mumakirogiramu. Maequations eramangwana atinofanira kurangarira.
Tisati tatsanangura mafrequency, tinofanira kutsanangura kuti mafungu emagetsi chii. Uyu munda wemagetsi unopararira kubva kune imwe nzvimbo (antenna, zuva, redhiyo, chero chii zvacho). Kufamba mumunda wemagetsi kune simba remagineti rakabatana nawo. Minda miviri iyi inoumba wave remagineti.
Nyika yese inobvumira mafungu aya kutora chero chimiro. Asi chimiro chakakosha iwaya resine. Izvi zvakaratidzwa muMufananidzo 1. Mafungu emagetsi anosiyana zvichienderana nenzvimbo nenguva. Kuchinja kwenzvimbo kunoratidzwa muMufananidzo 1. Kuchinja kwenguva kunoratidzwa muMufananidzo 2.
Mufananidzo 1. Sine wave yakaratidzwa senzira yekutarisa nzvimbo.
Mufananidzo 2. Ronga mafambiro emusana senzira yenguva.
Mafungu anongogara kwenguva refu. Mafungu anodzokorora kamwe chete pasekondi imwe neimwe muchimiro che "T". Kana akanyorwa sebasa muchadenga, nhamba yemamita mushure mekudzokorora kwemafungu inopiwa pano:
Izvi zvinonzi wavelength. Frequency (yakanyorwa kuti "F") ingori nhamba yematanho akazara anopedzwa nemafungu musekondi imwe chete (kutenderera kwemakore mazana maviri kunoonekwa sekushanda kwenguva yakanyorwa 200 Hz kana 200 "hertz" pasekondi). Pamasvomhu, iyi ndiyo fomura yakanyorwa pazasi.
Kumhanya kwemunhu kunoenderana nehukuru hwenhanho dzake (wavelength) yakawedzerwa nekufamba kwaanoita (frequency). Kufamba kwemafungu kwakafanana nekumhanya. Kumhanya kwefungu ("F") kwakawedzerwa nehukuru hwematanho anotorwa nemafungu nguva yega yega ( ) inopa kumhanya. Fomura inotevera inofanira kurangarirwa:
Mukupfupikisa, mafrequency ndiyo nzira yekuyera kuti mafungu anotenderera nekukurumidza sei. Mafungu ese emagetsi anofamba nekumhanya kwakafanana. Saka, kana mafungu emagetsi akatenderera nekukurumidza kupfuura mafungu, mafungu anomhanya anofanirawo kunge aine marefu mapfupi. Marefu marefu zvinoreva marefu mapfupi.
