Dab dhaliyaha Signal: jaantuska iyo mabda 'hawlgalka. A matoor signal sinusoidal

Signal matoorrada - qalabka waxaa ugu horayn loogu talagalay in lagu tijaabiyo idaacadahaasi ay. Intaa waxaa dheer khabiiro u isticmaalaan si loo cabbiro dabeecadaha converters analog. model Test laliska dhacdaa by simulating signal. Waxaa lagama maarmaan ah si uu u hubiyo qalab ee waafaqsan heerka casriga ah. Signal si toos ah qalab lagu quudin kartaa foomka saafi ah ama dhalanrog ah. Its heerka of channels ku kala duwanaan karaan si weyn loo.

Sidee matoorka?

Haddii aan ka fiirsan model soo jireenka ah ee matoor signal a, bandhigay guddiga hore loo arki karaa. Waxaa lagama maarmaan ah in lala socdo gariirka iyo fuliyaan gacanta. At sare ee shaashadda waa editor ah oo bixiya noocyo kala duwan oo shaqooyin kala duwan. Next yimaado sevensor hoos ku, taas oo muujinaysa inta jeer gariirka ah. waxaana hoostiisa waa modeline. Heerka Ilodanimada signal ama barakac lagu xakameyn karaa laba badhamada. Si la files shaqayn gaar ah mini-bar. Iyada oo taageero ka natiijooyinka baaritaanka lagu kaydin karaa ama si degdeg ah u furan.

user The si ay u awoodaan in la beddelo inta jeer sampling ah, matoorka uu leeyahay jaangooyaha gaar ah. Tiro ahaan, aad si deg deg ah soo jiidasho leh waafajinta karaa. calaamadaha soo saarka, sida caadiga ah ku yaalla xagga hoose ee qalabka shaashad. Waxaa kaloo ka mid matoorka kiciya for qodayaa ah.

qalabka macmal ah

Samee matoor signal aad gacmihiinna waa dhibaato ay sabab u tahay dhibka ka mid ah qalabka. gabal ugu weyn ee qalabka waxaa loo arkaa inay xulista a. Waxaa loo qaabeeyey si ay u qaabeeyaan tiro cayiman oo channels. Wareeggeedii in qalabka sida caadiga ah waxa uu leeyahay laba. Si ay ula qabsadaan matoor inta jeer ee uu u baahan yahay synthesizer. Haddii aan ka fiirsan qalabka multi-channel, microcontrollers ku haboon yihiin taxane KN148. Converters waxaa loo isticmaalaa nooca analog oo kaliya.

Qalabka signal sinusoidal

Sinusoidal circuit signal matoor isticmaalaa fudud si caddaalad ah. Sammeecado kaliya nooca qalliinka loo isticmaali karaa. Waxaa lagama maarmaan ah signalka lacag gudbinta caadi ka resistors ah. Potentiometers ku jira nidaamka lagu qiimeeyo aan ka yarayn 200 ohms. wareegga waajib garaaca wadnaha ku xiran tahay habka tilmaame xawaaraha dhalin ah.

Waayo, tuners dabacsan rakibay qalabka multi-channel. kala duwan ee inta jeer ee signal matoor sinusoidal u beddelayo markii buro ee Rotary. Si ay u tijaabiso aqbalana waxaa haboon doonaa oo kaliya nooca modulating ah. Tani waxay soo jeedinaysaa in channels of matoor waa in ay ahaataa ugu yaraan shan.

Wadista oscillator low-soo noqnoqoshada ah

The matoor signal noqnoqoshada hooseeyo (nidaamka hoos ku qoran) waxaa ka mid ah resistors analog. Potentiometers waa in lagu dhejiyaa qiimaha of 150 ohms. Si aad u bedesho qiimaha taxane garaaca wadnaha ee loo isticmaalo KK202 modulators. Ahbaa kiiskan dhacdaa iyada oo capacitors ah. Inta u dhaxaysa resistors ee kicinta wareeg waa in la dhigay. Adigoo laba musmaarradii aad dhigay karaa matoor signal a (low) biiro.

Mabda'a hawlgala ee lagu daydo codka

Ku xiridda matoor calaamadaha loomana baahno ee danab inta jeer waxaa marka hore laga codsadaa in ay xulista ah. Dheeraad ah, talantaalli ah hadda maraa xidhmada transistors. Ka dib markii qaab beddelidda in ay shaqada ka mid capacitors. Isbedbedelka ka muuqataa shaashadda isticmaalaya microcontroller ah. Si ay ula qabsadaan xadka inta jeer ee u baahan boosteejada gaar ah chip.

Awooda wax soo saarka ugu badan in ay dhacdo ah matoor signal audio gaaro laga yaabaa 3 GHz ah, laakiin qaladka waa in ay ahaataa yar. limiter loo dhigay this dhow resistor ah. qaylada Phase loo arko by nidaamka ay sabab u tahay isku xira ee. Wajiga index isbedbeddelka ku xiran tahay oo kaliya on heerka qaab beddelidda hadda.

Scheme qalab signal isku qasan
