I-BEFACO PONY VCO Pulse Width Module
I-Pulsewidth Modulation (PWM)
Lapho kukhethwa i-Square waveform, ipharamitha ye-Timbre iphenduka ibe i-bipolar pulse-width modulation control (PWM). Ilawula inani lesikhathi isikwele esizoba sezingeni laso eliphezulu kumjikelezo ngamunye. Ngokuvamile kukalwa ngamaphesentitage yomjikelezo womsebenzi, ukuba u-50% womsebenzi womjikelezo (indawo emaphakathi yokulawula i-Timbre) indawo yokuqala lapho isikhathi isikwele sikuso esiphezulu nesisezingeni eliphansi silingana. I-pony VCO ibala ngebanga elikhulu le-PWM, elikwazi ukuthola ububanzi obuqinile be-pulse. Lokhu kuwusizo kakhulu ukwenza "intambo" ye-monophonic kanye "nekhorasi" njengemisindo usebenzisa amasignali angaphandle ukuwashintsha. Qaphela ukuthi ukufeza lobu bubanzi obuqinile be-pulse, isekethe ye-PWM ihlanganisa lonke uhla lomjikelezo womsebenzi. Lokhu kusho ukuthi endaweni encane nephezulu kakhulu ye-Timbre (0 kanye no-100% womjikelezo womsebenzi) ukuzulazula kuzoma.
- Bheka ngemuva kwemojuli lapho kufanele ubone khona izimbiza ezintathu zokunquma. Ezansi kwesokudla yi-V-Ref, kanti ezingaphezulu ziyi-Init (kwesokunxele) kanye ne-V/Oct (kwesokudla).
- Khetha i-multimeter yakho bese ukhetha i-DC Voltage mode (ivamise ukumakwa ngokuthi V=). Xhuma i-probe emnyama endaweni Ephansi (ungasebenzisa umkhono wekhebula lokuchibiyela elixhunywe kunoma iyiphi enye imojuli) bese ubeka uphenyo olubomvu oluthinta iphuzu elimakiwe.
Kufanele ufunde inani elizungeze i-2.5V. Lungisa ngokucophelela i-V-Ref trim-pot uze ubone i-2.500V ncamashi. Uma une-multimeter enhle (izibalo ezingu-6000 noma ngaphezulu) ekubonisa oziro abangu-4, uzokwazi ukulungisa lokhu ngokunembe nakakhulu. - Beka i-Freq Pot endaweni emaphakathi, i-Octave ishintshe iye endaweni yesibili (C2) kanye ne-Timbre slider endaweni encane. Khetha i-Sine waveform bese ubeka inkinobho ye-Range endaweni ye-Semitone Range. Hlola kabili zonke izilawuli futhi uma konke kusendaweni efanele, hamba esinyathelweni esilandelayo. Phakathi nezinyathelo ezimbili ezilandelayo, qiniseka ukuthi awuzihambisi izilawuli ze-Freq ne-Timbre. Njengoba lezo zilawuli zithinta imvamisa, noma yikuphi ukuhamba kuzo kuzothinta ukufunda kwakho
- Xhuma okukhiphayo kwemojula kokokufaka kweTuner yakho bese uhlola inothi elikubonisayo. Kufanele ibe seduze ne-C2. Lungisa i-Init trim-pot uze uthole u-C2 no-0 cent.
- Nyusa iswishi ye-Octave uye endaweni yesihlanu (emakwe ngokuthi 0 kuphaneli engaphambili) bese uhlola Ishuna. Inothi kufanele lisondele ku-C5. Lungisa i-V/Oct trim-pot ngokucophelela uze uthole u-C5 no-0 cent.
Buyela endaweni ye-C2 ekushintsheni kwe-Octave futhi uhlole ishuna. Uma ikubonisa i-C2 enembile (phakathi kwamasenti angu-0-5), hlola amanye ama-octave. Kufanele uthole i-C1 kuye ku-C7 ngokunemba okufanayo. Uma kungenjalo (okungaba icala elivamile), phinda izinyathelo 4 no-5 uze uthole ukunemba okuhle kuyo yonke i-octave. Le nqubo isekelwe ekuphindaphindweni kwezinyathelo 4 no-5 ngakho ungakhathazeki uma kuthatha isikhashana ukuthola ukushuna okulungile. Inani lokuphindaphinda okudingekayo ukuze uthole ukulinganisa okuhle lihlukile kuwo wonke amayunithi.
