Harmonics inobatsira iwe kusiyanisa zviridzwa zvakasiyana-siyana zvemimhanzi
Kana iwe wakadzidza chero kurangwa kweacoustics , redio signal teknolojia, kana michina yemagetsi, unogona kuyeuka kuvhara musoro weHarmonic frequency. Icho chikamu chinokosha chekuti mimhanzi inonzwika sei uye inozivikanwa. Harmonic frequency ndiyo imwechete iyo inotibatsira kunyatsonzwisisa hutano hwakasiyana-siyana hwezvinhu zvakagadzirwa nezviridzwa zvakasiyana-siyana, kunyange pavanenge vachitamba rimwechete.
Tsanangudzo yeHarmonic Frequency
A fremonic frequency inogara ichidzoka uye ichidzokorora kazhinji yepakutanga yemafunguro, iyo inozivikanwa senheyo huru. Kana iyo yakasvibirira yakaiswa pa 500 hertz , inosangana nehanzvadzi yekutanga yehurmonic pa 1000 hertz, kana kaviri iyo inowanzobuda. Chechi yechipiri harmonic inowanikwa pa 1500 hertz, iyo katatu iyo inowanzo inowanzo, uye yechitatu harmonic frequency ndeye 2000 hertz, iyo inowirirana kane nguva inokosha, nezvimwe zvakadaro.
Mune rimwe muenzaniso, harmonic yekutanga yevhangeri huru 750 hertz ndiyo 1500 hertz, uye yechipiri harmonic ye 750 hertz is 2250 hertz. Zvose zvinokonzerwa nehurumende zvinowanzoitika panguva yakakura uye zvinogona kuputsika mukati mezvikamu zvakasiyana-siyana uye zvinyorwa.
Migumisiro yeHarmonic Frequency
Zvinenge zvose zviridzwa zvinoumba unhu hunomira humiriri hwomukati hune zvose zvinodiwa uye zvinowirirana. Kunyatsorongeka kwezvivako izvi kunobvumira nzeve yomunhu kuti ione kusiyana kwemashoko maviri ekuimba nenziyo pamwe chete pamusana mumwechete (kuwandisa) uye izwi (amplitude). Izvi ndizvowo zvatinoziva kuti gitare rinonzwika segitare uye kwete eboe kana hwamanda kana piano kana dhiramu. Kana zvisina kudaro, munhu wose nezvose zvinonzwika zvakafanana. Vaimbi vane unyanzvi vanogona kuisa zviridzwa nekuteerera uye kuenzanisa maitiro ehurmonic pakati pekugadzirisa.
Harmonics Versus Overtones
Izwi rokuti "overtones" rinowanzoshandiswa mukukurukurirana rinosanganisira harmonic frequencies. Kunyange zvazvo zvakadaro-yechipiri harmonic ndiyo yepamusoro yepamusoro, harmonic yechitatu ndeyepiri yepamusoro, uye zvakadaro-mazwi maviri ari echokwadi akasiyana uye akasiyana. Overtones inobatsira kune huwandu hwehutano kana chirevo chechidimbu chinonzwika.
Harmonic Frequency Distortion in Vatauri
Vatauriri vane basa rekubudisa mahedheni akarurama ehurmonic yezviridzwa zvavanoita. Kuti kuenzanise musiyano pakati pemisere inouya uye yakabuda yevakurukuri, tsanangudzo ye Total Harmonic Distortion (THD) inogoverwa kune umwe neumwe mukurukuri-iyo yakaderera chikamu, zviri nani mutauri wekutaura kwezwi. Somuenzaniso, THD ye055 inoreva kuti 0.05 muzana yemutinhiro unobva kumukurukuri unosvibiswa kana kuti wakasvibiswa.
Izvozvi zvinotarisirwa kumutengesi kumusha nokuti vanogona kushandisa matanho eTD akarongerwa kuti ave mukurukuri kuti aongorore hutano hwakanaka hwavanogona kutarisira kuwana kubva kumukurukuri. Zvechokwadi, kusiyana kwezvirimani kune zvishoma, uye vanhu vakawanda zvichida havazocherechedzi hafu yepakati pamusiyano muTV kubva pane imwe hurukuro kusvika kune inotevera.
Zvisinei, apo harmonic frequency inokanganisa ne1%, zvigadzirwa zvekurekodha zvisinganzwisisiki, saka kuchenjera kugara kure nevatauri pamucheto wakakwirira weT THD.
