Kwakwalada Lissajous na CRO ko Cathode Ray Oscilloscope

IEE-Business Cathode Ray Oscilloscope (CRO) wani alama mai mahimmanci a cikin wurare elektronika. CRO yana da muhimmanci a kan bincike na tsari na fadada dabbobi. Babban baka na CRO shine CRT (Cathode Ray Tube). Wani abubuwa na CRT ta shahara a nan-

Idan ana kula da duk biyu na deflection plates (horizontal deflection plates da vertical deflection plates) na CRO (Cathode Ray Oscilloscope) zuwa biyu na sinusoidal voltages, za suka faru Lissajous pattern a skirrin CRO. Tsarin Lissajous patterns yana canza idan an canza phase difference bayan signal da ratio na frequencies wadanda ake kula zuwa deflection plates (traces) na CRO. Wannan yana taimakawa a kan bincike na signals wadanda ake kula zuwa deflection plates na CRO. Lissajous patterns na biyu na Applications don bincike na signals. Don gyara phase difference bayan biyu na sinusoidal signals wadanda suka da frequency sama. Don haɗa ratio na frequencies na sinusoidal signals wadanda ake kula zuwa vertical da horizontal deflection plates.

Calculation of the phase difference between two Sinusoidal Signals having same frequency

Idan ana kula biyu na sinusoidal signals wadanda suka da frequency da magnitude sama zuwa biyu na deflection plates na CRO, Lissajous pattern yana canza idan an canza phase difference bayan signals wadanda ake kula zuwa CRO. Tsarin Lissajous patterns wadanda suka faru a matsayin phase difference bayan signals ta shahara a nan-

SL No.	Phase angle difference ‘ø’	Lissajous Pattern appeared at CRO Screen
1	0o & 360o
2	30o or 330o
3	45o or 315o
4	60o or 300o
5	90o or 270o
6	120o or 240o
7	150o or 210o
8	180o

An fi sani biyu na cases don tabbatar da phase difference ø bayan biyu na signals wadanda ake kula zuwa horizontal da vertical plates,

Case – I: Idan, 0 < ø < 90o ko 270o < ø < 360o : –
Kamar yadda aka bayar a nan, ya danganta cewa idan angle ya zama a gaba 0 < ø < 90o ko 270o < ø < 360o, Lissajous pattern yana da tsari na Ellipse wadanda major axis yake zama ta shiga daga first quadrant zuwa third quadrant:
Za ka iya duba misal a matsayin 0 < ø < 90o ko 270o < ø < 360o, kamar yadda aka nuna a nan-

A wannan yanayin, phase difference yana zama-
