Tom ntej no, peb yuav txuas 100K resistor rau - sab ntawm lub capacitor.

Kauj Ruam 33: Cov lus tawm tswv yim Resonance Resistor

Tus txiv leej tub no zoo ib yam li 10uF capacitor, tab sis nws muaj peev xwm siab dua, ntawm 100uF. Koj lub 100uF capacitor yuav zoo dua.

Txuas lub + sab ntawm lub capacitor mus rau nruab nrab txhais ceg ntawm transistor uas txuas rau "sab xis" sab ntawm diode ntaiv.

Txuas lub - sab ntawm lub tshuab hluav taws xob mus rau ib qho ntawm cov xaim xaim uas koj rub tawm ntawm PS2 maub los cable koj tus muam tus npua npua zom los ntawm. Los xijpeem.

Lwm sab ntawm tus guinea-npua-hloov pauv hlau mus rau tus pin 9 ntawm LM13700, tab sis thaum kuv muaj ob daim duab ntawm cov xaim txuas rau lub tshuab hluav taws xob, kuv tsis muaj ib daim duab qhia lwm sab ntawm xaim. Yog li tshawb xyuas daim duab uas kuv tau suav nrog. Saib? Pin 9, tus pin kaum …? OH Kuv Cov Lus Kuv nyuam qhuav pom tias koj tuaj yeem tsim cov ntawv sau rau ntawm cov duab. Kuv yuav ua li ntawd.

Kauj Ruam 34: Tsuas yog ob peb lub zog ntsuas

Nov yog ob lub 100K potentiometers. Kuv nyiam hom lauj kaub no vim tias lawv pheej yig heev, thiab lawv tuaj yeem hloov pauv sai heev. Lawv tsis xav tias raug thiab lawv yuav hnav sai dua li cov lauj kaub tais diav, tab sis hav, kev sib pauv, kuv puas yog?

Koj tuaj yeem siv txhua hom potentiometer uas koj nyiam, kaw, kim, rov ua dua lossis rov tsim dua, thiab txawm tias qhov txiaj ntsig sib txawv yuav ua haujlwm tau zoo nrog lub Circuit Court no, los ntawm 10K txog 1M. Qhov sib txawv tsuas yog nyob hauv yuav ua li cas qhov ntsuas hluav taws xob teb rau "kev ua" ntawm kev sib tw pob qhov rooj.

Kauj Ruam 35: Peb Cov Pots Tau Txais Voltage

Kuv xav txog potentiometers raws li muaj sab "siab" thiab sab "qis". Muaj lub wiper sab hauv lub zog loj uas ua raws lub pob qhov rooj, rub tawm tsam 3/4 lub voj voos ntawm cov khoom tiv taus. Thaum peb tig lub ntim "nce" txhua txoj kev, peb tab tom nqa tus pin nruab nrab txuas mus rau "siab" txhais ceg ntawm lub zog.

Hauv qhov kev tsim no, ob lub zog tau txais + hluav taws xob rau "siab" txhais ceg. Ob leeg tau hauv av ntawm lawv txhais ceg "qis".

Kauj Ruam 36: Resonance Hauv Kev Tswj

Muaj 220K tus tiv thaiv txuas nrog rau nruab nrab ceg ntawm transistor uas tau dai tawm ntawm LM13700 nti. Tus resistor tau txuas nrog rau nruab nrab txhais ceg ntawm ib qho ntawm cov potentiometers. Ib qho twg! Peb tsuas yog yuav tsum tau nco kom peb tuaj yeem txhim kho nws hauv qhov chaw raug.

Tsis tas li ntawd, nco ntsoov qhov kuv tau tham txog txoj kev rov qab thaum peb tab tom cuam tshuam nrog ib feem ntawm qhov Circuit Court. Yog tias koj xav tau CV-tswj tau resonance, qhov no yog qhov chaw ua qhov ntawd.
