The two signals S1 and S2, shown in figure, are applied to Y and X deflection plates of an oscilloscope.   The waveform displayed on the screen is Correct Answer <img alt="F1 Uday Madhu 03.07.20 D 7" src="//storage.googleapis.com/tb-img/production/20/07/F1_Uday_Madhu_03.07.20_D%207.png">

S1 → applied to y → vertical plates

S2 → applied to x → horizontal plates

Observing the waveform, we conclude that

For 0 < t < T/2, 0 < S1 < 1 and S2 = 1

And at t = T/2, S1 = S2 = 0

For T/2 < t < T, 0 > S1 > - 1 and S2 = 1

We can represent this data in tabular form

 t

 (x, y)

 0

 (+1, 0)

 T/4

 (+1, +1)

 T/2

 (+1, 0) and (-1, 0)

 3T/4

 (-1, -1)

 T

 (-1, 0) and (+1, 0)

 

Thus the waveform displayed on the CRO screen is,
