Kana zvasvika pakuchengetedza kunatswa kwakachena, pane zvinhu zvakasiyana-siyana zvekucherechedza nekufungisisa. Kunyange zvazvo vaduku-vanozivikanwa kune vakawanda, Intermodulation Distortion (yakafuridzirwa seM IMD) inogona kunge yakanyanyisa kana ikadzorera musoro wayo wakaipa, unoyevedza. Kusiyana nedzimwe mhando dzekuvhiringidzika kwemimhanzi, Intermodulation Distortion inonyatsooneka kune nzeve uye inogona kuva imwe yezvinonyanya kuoma kuderedza mitambo yemanzwi.
Chii Chinonzi Kuparadzaniswa Kwemakemikari?
Kuparadzaniswa kweCopmodulation inowanzoonekwa semagadziridziro kana kuti pre-amplifier specification (asi inogona kuvapo kune mamwe mashizha ehurukuro sevatauriri, CD / DVD / media player, nezvimwewo) iyo inoshandura mafungiro asingaiti harmonic akawedzerwa kune chiratidzo chekupinza. Kufanana neHalonic Distortion Total, Kuparadzaniswa kweChirongwa chekunyora kwemashoko kunotaridzirwa uye kunomirirwa semapatendi ehuwandu hwehuwandu hwemashoko. Uye sezvakangoita neHotoni Harmonic Distortion, nhamba shoma dziri nani pakuvandudza kushanda.
Intermodulation Distortion inogona kuitika kana zviratidzo zviviri kana kupfuura zvinosanganiswa kuburikidza nedhiyo isina kusimba. Chimwe nechimwe chemashoko chinoshanda pamwe chete, zvichigadzira kuchinja (kana modulated) amplitudes. Izvi zvinoguma pakuumbwa kwemaferensi - anowanzozonzi "sidebands" - haasipo mune chiratidzo chekutanga. Sezvo izvi zvikamu zvakasiyana-siyana zvinokwira pane zvakakwana uye kusiyana kwezvinyorwa zvepakutanga, zvinonzi hazvisi-harmonic uye zvisingadikanwi nekuda kwechimiro chisina kufanana.
Kuti uenzanisire, taura kuti chiridzwa chimwe chinonyora uye chinobudisa nguva inowanikwa ye440 Hz. Harmonic frequencies (nhamba dzakawanda dzezvakakosha) kuti chimbo chimwe chiitike pa 880 Hz, 1220 Hz, 1760 Hz, nezvimwewo. Kana yakagadzirisa inogadzira nguva isiri-harmonic yeHz 300 Hz pamwe chete nehuwandu hwehuwandu hwe440 Hz, yechitatu yeenhamba ye 740 Hz ichadzorerwa (440 Hz + 300 Hz), uye 740 Hz haisi harmonic ye 440 Hz. Nokudaro, inonzi Intermodulation Distortion nokuti iri pakati pemafungiro ehurmonic.
Nei Kuparadzaniswa Kwemasimudziro Kunokosha
Sezvo Intermodulation Distortion isinganzwisisiki (kwete harmonic), iine chirevo chinogutsa. Uye pazvinenge zviripo, zviri nyore chaizvo kutora nenzeve kudarika kusvibiswa kwehurmoni, sezvo harmonics inowanzovapo mumasaini anoteerera chero zvakadaro. Asi pamvura yakadzika yepamusoro uye / kana nemimwe mimhanzi iri nyore, Intermodulation Distortion inogona kunge isina kuonekwa. Kusiyanisa tones kunogona kunzwika zvakajeka. Asi kamwechete izwi rinowedzera kusvika pane imwe nzvimbo iyo isiri misiyano inoitika mukati mekusimudzira, kushandurwa uye chido chisingadikanwi chezvivako zvevhu kana kuti chinosvibisa chiratidzo chepakutanga.
Izvi zvinowedzerawo nemhando dzakawanda dzemimhanzi mimhanzi (semuenzaniso orchestra) apo kune kukurukurirana kukuru pakati pezviitiko zvose. Uye chigumisiro chinogona kunge chiri chigadzirwa chemuti wecherechedzo iyo inobudirira inokonzera sonic tsanangudzo uye yakarurama. Pakupedzisira, Intermodulation Distortion inotungamirira kumhanzi asinganzwisisiki, akafukidzwa, kana asina upenyu. Pakaipisisa, zvinhu zvose zvinonzwika zvakaoma uye / kana zvakakomba zvakakomba.
Zvisinei, sezvakaitwa neHotoni Harmonic Distortion, Kuparadzaniswa kweKutaurirana kwevanhu kunowanzova kwakadzika zvokuti hakunzwisisiki. Zvizhinji zvemazuva ano zvakagadzirwa zvakanaka zvakakwana kuita kuti Intermodulation Distortion isakoshi. Ingoyeuka kuti nzeve dzako ndiyo mutongi ari nani wehutano hwakanaka, saka usatonga zvinongorori chete nemashoko ekuti Intermodulation Distortion.
