To the y-input of a CRO a signal defined by 10 sin 100t is applied. To the x-input the signal 10 cos 100t is fed. The gain for both x-channel and y-channel is the same. The screen shows
-
- sinusoidal
- a straight line
- an ellipse
- a circle
Correct Option: D
x² + y² = 10² | sin² (100 t) + cos² (100 t)| = 100, which is constant
Hence the circle.
