Usoro ahịrị n'ime band: Ihe njiri mara njirimara a bụ ngbanwe akụkụ nke mgbama a na-ebufe na paspọd. Ihe nzacha emere site na ọrụ nzaghachi nkeji ahịrị nwere ezigbo ahịrị usoro.
Isi nhazi
Kewara n'ime nzacha analọg na nzacha dijitalụ dịka mgbama a na-ahazi.
A na-ekewa ụzọ nke ngafe nke nzacha na-agafe agafe na ngafe dị ala, ngafe dị elu, bandpass, na nzacha ngafe niile.
Ihe nzacha ngafe dị ala:ọ na-ekwe ka ihe ndị dị ala ma ọ bụ DC dị na mgbaàmà gafere, na-egbochi ihe dị elu ugboro ugboro ma ọ bụ nnyonye anya na mkpọtụ;
Nzacha dị elu: ọ na-ekwe ka ihe dị elu ugboro ugboro na mgbaàmà gafere, na-egbochi obere ugboro ma ọ bụ DC components;
Band ngafe iyo: Ọ na-enye ohere ka a gafefe akara, akara nbichi, nnyonye anya, na mkpọtụ n'okpuru ma ọ bụ n'elu igwe;
Ihe nzacha na-agbaze: Ọ na-egbochi mgbaama n'ime ụfọdụ bandwit na-enye ohere akara ndị ọzọ na-abụghị otu, nke a makwaara dị ka nzacha notch.
Ihe nzacha gafere niile: Ihe nzacha na-agafe agafe pụtara na njupụta nke mgbaàmà agaghị agbanwe n'ime oke zuru oke, ya bụ, uru njupụta nke oke zuru ezu bụ nhata 1. A na-eji ihe nzacha ihe niile na-agafe na-eme ihe na-eme ka oge na-aga n'ihu, ya bụ, usoro nke mgbaàmà ntinye na-agbanwe, na ihe kachasị mma bụ na ntụgharị oge na-adabere na ugboro ole, nke kwekọrọ na usoro nkwụsịtụ oge.
Ma akụrụngwa eji eme ihe bụ ma ihe nzacha na-agafe agafe ma na-arụ ọrụ.
Dabere na ntinye nke nzacha, a na-ekewakarị ya na nzacha efere na nzacha panel.
Na bọọdụ, wụnye na bọọdụ, dị ka PLB, usoro nzacha JLB. Uru nke nzacha a bụ nke akụ na ụba, na ọghọm ya bụ na nzacha ugboro ugboro adịghị mma. Isi ihe kpatara ya bụ:
1. Enweghị ikewapụ n'etiti ntinye na ntinye nke nzacha, nke na-adịkarị mfe ijikọta;
2, impedance grounding nke nzacha adịghị ala nke ukwuu, na-ebelata mmetụta ugboro ugboro ugboro ugboro;
3, otu njikọ dị n'etiti nzacha na chassis ga-emepụta mmetụta abụọ na-adịghị mma: otu bụ nnyonye anya electromagnetic nke oghere dị n'ime chassis, nke a na-ebute ozugbo na eriri a, n'akụkụ eriri ahụ, na-amụba nzacha site na eriri ọkụ. Ọdịda; nke ọzọ bụ na a na-enyocha nnyonye anya mpụga site na nzacha nzacha na bọọdụ ahụ, ma ọ bụ na-emepụta radieshon ozugbo ma ọ bụ ozugbo na sekit na bọọdụ sekit, na-ebute nsogbu uche;
A na-etinyekarị efere nzacha, njikọ nzacha na ihe nzacha panel ndị ọzọ na ogwe igwe nke chassis mkpuchi. Ebe ọ bụ na a na-etinye ya ozugbo na metal panel, ntinye na mmepụta nke nzacha ahụ dịpụrụ adịpụ kpamkpam, ala dị mma nke ọma, a na-ehichapụkwa nnyonye anya na eriri n'elu ọdụ ụgbọ mmiri chassis, ya mere mmetụta nzacha dị mma.
Ihe nzacha na-agafe agafe bụ sekit nzacha nke na-eji resistor, reactor na akụrụngwa capacitor. Mgbe ugboro ugboro nke resonant, uru nke impedance sekit dị ntakịrị, na ihe mgbochi sekit dị ukwuu, a na-emezi uru akụkụ sekit ka ọ bụrụ njirimara harmonic ugboro, na harmonic ugbu a nwere ike ihicha; mgbe ọtụtụ frequenses harmonic A na-emepụta sekit n'iji ya gee ntị, mgbe ahụ enwere ike ịchachaa njirimara kwekọrọ ugboro ugboro, na nzacha nọmba harmonic (3, 5, 7) na-enweta site na obere mgbochi impedance. Ụkpụrụ bụ isi bụ maka ọnụ ọgụgụ dị iche iche nke harmonics, ịmepụta ugboro ole harmonic dị ntakịrị, na-enweta mmetụta nkewa nke ugbu a, na-enye ụzọ ntụgharị maka prefiltered elu harmonics iji nweta ịdị ọcha waveform.
Enwere ike kewaa ihe nzacha na-agafe agafe na nzacha capacitive, sekit nzacha ihe ọkụkụ ọkụ, sekit nzacha L-RC, sekit nzacha RC nwere ụdị π, sekit nzacha RC nke ọtụtụ akụkụ, na sekit nzacha LC nwere ụdị π. Pịa ka ịrụ ọrụ n'ime otu nzacha nlegharị anya, nzacha nlegharị anya abụọ, na nzacha ngafe dị elu. Ihe nzacha na-agafe agafe nwere uru ndị a: usoro ahụ dị mfe, ọnụ ahịa ntinye ego dị ala, na ihe na-emeghachi omume na usoro ahụ nwere ike ịkwụ ụgwọ maka ihe ike na usoro. Ọ na-eme ka ihe ike nke grid dịkwuo mma; nkwụsi ike na-arụ ọrụ dị elu, mmezi ahụ dị mfe, teknụzụ maturation, wdg. A na-ejikarị ya eme ihe. Enwere ọtụtụ akụkụ nke adịghị ike nke ihe nzacha na-agafe agafe: mmetụta nke grid grid ike, uru nke impedance usoro na ọnụ ọgụgụ isi nke resonant frequencies na-agbanwekarị dị ka ọnọdụ ọrụ; ihe nzacha harmonic dị warara, naanị ọnụ ọgụgụ isi nke oge bụ isi naanị enwere ike ịchacha Harmonics, ma ọ bụ n'ihi ihe ndị yiri ya, na-abawanye harmonics; nhazi n'etiti nzacha na nkwụghachi ụgwọ ọrụ na nhazi nrụgide; dị ka nke ugbu a na-asọfe site na nzacha, ọ nwere ike ime ka arụ ọrụ nke akụrụngwa buru ibu; Ihe eji eme ihe na-ebuwanye ibu, ibu na olu buru ibu; nkwụsi ike arụmọrụ adịghị mma. Ya mere, ihe nzacha na-arụ ọrụ na-arụ ọrụ nke ọma na-abawanye ngwa ngwa.
Anyị nwekwara ike hazie rf pasive components dị ka ihe ị chọrọ. Ị nwere ike itinye ibe nhazi iji nye nkọwapụta nke ịchọrọ.
