Igabanyirizwa rya Frequency 256, Frequency yinjiyemo ni 0.3 ~ 30GHz

Igabanyirizwa rya frequence ya 256 ni module ya digitale circuit igabanya frequence y'ikimenyetso cyinjiye kuri 1/256 cy'irequence yacyo y'umwimerere. Imiterere n'imikorere yacyo ni ibi bikurikira:

Ibiranga:
1. Igipimo cyo kugabanya inshuro nyinshi
Igipimo cyo kugabanya inshuro ni 256: 1, gikwiriye ibintu bisaba kugabanya inshuro cyane, nko gukora ibimenyetso byo kugenzura inshuro nke biturutse ku masaha afite umurongo munini.
2. Imiterere y'ibisasu by'urwego rwinshi
Ubusanzwe igizwe n'ibipimo by'ibinyabiziga by'urwego rwa 8 (nk'ibipimo bya 8-bit), nka 2 ^ 8 = 256, hagomba guhindurwamo ibice byinshi, bishobora gutera gutinda kwangirika.
3. Ihererekanya ry'umusaruro
Uruhererekane rw'imirimo (duty cycle) rw'umusaruro munini wa binary counter ni 50%, ariko icyiciro cyo hagati gishobora kuba kidahuje. Niba hakenewe uruhererekane rw'imirimo rwa 50% rw'uruziga rwuzuye, hakenewe uburyo bwo gusesengura logique (nk'uburyo bwo gusubiza ibitekerezo cyangwa guhuza uruhererekane rw'imirongo).
4. Gutuza cyane
Hashingiwe ku miterere y’urusobe rw’amakuru mu buryo bwa digitale, ifite ubushobozi bwo gutanga umusaruro mwinshi, ntigira ingaruka nyinshi ku bidukikije nk’ubushyuhe n’amashanyarazi, kandi ishingira ku buryo ikimenyetso cy’itumanaho gihoraho.
5. Ingufu nke zikoreshwa kandi zihuzwa
Ikoranabuhanga rya CMOS rigezweho rikoresha ingufu nke, ryoroshye kurishyira muri FPGA, ASIC cyangwa microcontroller, kandi ritwara umutungo muke.

Porogaramu:
1. Sisitemu y'itumanaho
Guhuza frequency: Muri phase-locked loop (PLL), target frequency ikorwa hamwe na voltage controlled oscillator (VCO); Local oscillator (LO) frequency division muri RF applications ikora multi-channel frequencies.
2. Gutunganya ibimenyetso by'ikoranabuhanga
Gupima ingero nke: Kugabanya igipimo cy'ingero kugira ngo ugabanye umubare w'amakuru, bikoreshwa hamwe no kugabanya uburyo bwo gusesengura amakuru.
3. Ibikoresho byo kumenya igihe n'igihe
Mu masaha ya elegitoroniki n'igihe cy'ikoranabuhanga, oscillator ya kristale (nka 32.768kHz) igabanywamo 1Hz kugira ngo itware igice cya kabiri.
Gutinda gutangira imirimo cyangwa gahunda y'imirimo rimwe na rimwe mu kugenzura imikorere y'inganda.
4. Ibikoresho byo gupima no gupima
Imashini itanga ibimenyetso ikora ibimenyetso byo gupima inshuro nke cyangwa igakora nk'uburyo bwo kugabanya inshuro z'amajwi ku gipimo cy'amajwi.
