Question

An oscilloscope shows a steady sinusoidal signal of 5 Volt peak to peak, which spans 5 cm in vertical direction on the screen. By tweaking the time sweep, the periodic saw-tooth voltage of the oscilloscope is replaced by voltage signal identical to the one that is detected. What will be observed on the oscilloscope screen?

Answer 1

Answer:

it will show a continuous rise in value. The rise will be sinusoidal.

Explanation:

Answer 2

The thing that will be observed on the oscilloscope screen is a diagonal line on the screen.

What is an oscilloscope?

It should be noted that an oscilloscope is a type of electronic test instrument which graphically displays varying signal voltage as a calibrated two-dimensional plot of the signals as a function of time.

In this case, instead of using the time base saw tooth to drive the horizontal deflection, then one can use an external sinusoidal input signal to drive the horizontal deflection and this will result in a diagonal line on the screen.
