a. Mtundu wa Qualtz LOCKed: Amagwiritsa ntchito oscillator ya quartz kuti apange mayendedwe olondola komanso okhazikika opatsirana ndi kulandira. Dera ndi losavuta ndipo mtengo wake ndi wotsika. Ndiwo mawonekedwe amakono a maikolofoni amakono opanda zingwe. Maikolofoni yamtunduwu ndi yolandirira imatha kuphatikizidwa ndi pafupipafupi kamodzi, ndipo kuchuluka kwake sikungasinthidwe kapena kusinthidwa.

b. Mtundu wopangidwa ndi PLL: Kuti mupewe maikolofoni opanda zingwe omwe angasokonezedwe ndi zizindikiritso zina panthawi yogwiritsira ntchito, singagwiritsidwe ntchito, kapena kugwiritsa ntchito maikolofoni angapo nthawi imodzi, ndikofunikira kusintha njira mosavuta komanso mwachangu nthawi iliyonse, kotero The kapangidwe ka dera ka PLL kalandiridwa kuti akwaniritse zofunikira pantchitoyi.

Malinga ndi wolandila a. Mtundu wa njira imodzi: Chokhacho chokhacho cha wolandila ndi njira imodzi yokha yosasankha yokha kapena yolandirira yokha. Yoyamba ilibe msika ku Taiwan, koma msika wogulitsa kunja uli ndi mtengo wotsika mtengo. Chinthu chimodzi (katundu wamitundu yayikulu). Yotsirizira ndiyo njira yabwino kwambiri yogwiritsira ntchito njira zingapo munthawi yomweyo m'malo aukadaulo chifukwa chogwiritsa ntchito mosavuta komanso mawonekedwe okhazikika kuti musasokonezedwe ndi ma siginolo.

b. Mtundu wapawiri: Ngati wolandila, njira ziwiri zokha kapena zosankha zokha zimakhala ndi mwayi wogwiritsa ntchito bwino mulanduwo ndikuchepetsa mtengo. Yoyambayi ndi yotchedwa "ndege yankhondo yankhondo yaku Asia", chifukwa cha kapangidwe kake kosavuta, yakhala chitsanzo chachikulu cha omwe amapanga mitengo yotsika mtengo ku Taiwan. Zomalizazi sizovuta kuthana ndi kusokonezedwa kwamkati ndi kusakanikirana kwa ma antenna ndi kufanana chifukwa cha makina ake ovuta komanso dera. Imapezeka kwa opanga ochepa omwe amapanga mitundu yaukadaulo.

c. Mitundu yamawayilesi angapo: Ponena za wolandila, olandila omwe ali ndi njira zopitilira zinayi amasonkhanitsidwa, ndipo ambiri aiwo amatengera mapangidwe amakanema olandila modular. Ndizofunikira makamaka pakagwiritsidwe ntchito kazoyeserera.
