Iyo fease moducator idunhu umo chikamu chevatakuri chiverengero chinodzorwa nechiratidzo chinosemesa. Kune marudzi maviri eSine Wave Movie Modulation: Direct phase modulation uye zvisina kunanga phase modulation. Iyo nheyo yekunyorwa kwepakati kuti ishandise chiratidzo chekushandura zvakananga kushandura zvakananga paramita Iyo isina kunanga phase nzira yekutanga inosimbisa iyo amplitude of the Wasodulated wave, uye wozoshandura shanduko yemukati muchikamu chekuchinja, kuitira kuti uwane modulation. Iyi nzira yakagadzirwa neArmstrong muna 1933, inonzi Armstrong modulation nzira
Chikwangwani chemagetsi microwave phaase shifter ndeye maviri-chiteshi network inoshandiswa kupa musiyano wepakati uye yekuisa chiratidzo chinogona kudzorwa nechiratidzo chekudzora (kazhinji dc bias voltage). Huwandu hwekuchinja chikamu chinogona kusiyana neyakagadzika chiratidzo kana pane yakadzvanywa discrete kukosha. Ivo vanonzi Analog phase shifters uye digital chikamu chinoshatisa zvakateerana. Iyo phase modulator ndeye binary chikamu chekuchinja Keying Modulator muMicrowave Kutaurirana system, iyo inoshandisa kuenderera mberi Screen wave kuti unyanidze chitunha chiratidzo. Sine Wave Modase Modulation inogona kukamurwa kuti ive yakananga chikamu chekujairana uye kusanzwisisika phase modulation. Nekushandisa hukama iyo sine wave Iyo inonyanya kushandiswa zvakananga chikamu cheModulator Circuit ndeyekuvanya diede phose modulator. Dunhu rinoregedzera redhaka rinonyanya kuoma pane rakaoma pane iyo yakatwasuka chikamu circulation redunhu. Nheyo yayo ndiyo nzira imwe yemitambo yekutakurisa inoshanduka neye 90 ° chikamu chinja uye chinopinda mumamiriro ekunze emusoro-modulate kuti udzivise kujairwa kweMepler. Mushure mekufemerwa kwakakodzera, iyo yakawanikwa chiratidzo inowedzerwa kune imwe nzira yeinotakura kuti ubudise iyo yekufambisa-inosimbisa chiratidzo. Dunhu iri rinoratidzwa neakakwirira frequency kugadzikana, asi iyo shift shift haigone kuve yakakura (kazhinji isingasviki 15 °) kana kukanganisa kwakanyanya. Mhedzisiro yakapfava inowanzo shandiswa muFM Broadcast Transmitters.
