Correct Answer - Option 2 : 36°
Oscilloscope:
- An oscilloscope display voltage or current as a function of time.
- The sweep generation provides a periodic voltage waveform that varies with time.
-
When sweep and signal frequencies are equal, a single cycle appears on the screen.
- When the sweep frequency is lower than the signal frequency, several cycles appear on the screen.
- When the sweep frequency is higher than the signal frequency, less than one cycle appears.
- The display of the spot on the screen appears stationary only when the two frequencies i.e. sweep and signal are the same or integral multiples of each other.
- 1 Time period is the time taken to complete one-cycle or 360° electrical.
Time period (T) is inverse of frequency (f)
\(T = \frac{1}{f}\)
Calculation:
Given:
f = 1 Hz
\(T = \frac{1}{f} = \frac{1}{1} = 1 = 1000\;ms\)
1000 ms ↔ 360°
\(100\;ms \leftrightarrow \frac{{360^\circ }}{{1000\;ms}} \times 100\;ms = 36^\circ \)
∴ The phase difference between the signal is 36°.
