The sweep generator of a CRO is used to produce :
Answer: D
The sweep generator produces a sawtooth voltage for the horizontal deflection of the electron beam.
The time base must move the spot across the screen from left to right at a constant speed, so that horizontal distance represents time, and then return it quickly to the left to start again. A sawtooth does exactly this: a linear ramp for the trace and a fast drop for the retrace. It is applied to the horizontal (X) deflection plates.
The vertical plates receive the signal under observation, from the vertical amplifier, not the sweep. A sinusoidal sweep would move the spot at a varying speed and distort the time scale, so it is used only in special cases such as Lissajous patterns.
