What is the main function of the vertical amplifier in a Cathode Ray Oscilloscope (CRO)?

It amplifies the input signal to be displayed on the screen of the CRT.

Fill in the blank: The ______ produces a sawtooth signal, which is useful for horizontal deflection of the electron beam.

Time base generator

True or False: The delay line in a CRO is used to amplify the input signal.

False. The delay line provides a delay to the signal output from the vertical amplifier.

What does the frequency of a periodic signal relate to mathematically?

The frequency, f, is the reciprocal of the time period, T, represented as f = 1/T.

Riddle: I create luminous spots from electrons, helping you visualize signals. What am I?

Cathode Ray Oscilloscope (CRO)

Which component in a CRO controls the number of electrons emitted from the cathode?

Control grid

Fill in the blank: The ______ is responsible for producing high and low voltages in a CRO.

Power supply

True or False: In a Digital Storage Oscilloscope (DSO), data is stored before being displayed on the screen.

True.

What is the purpose of the graticule in a CRO?

To serve as a scale for amplitude measurements.

MCQ: What type of sweep is used in a CRO for periodic waveforms? A) Free Running B) Manual C) Continuous D) Random

A) Free Running

Fill in the blank: The deflection plates in a CRO are used to control the ______ of the electron beam.

Trajectory

Riddle: I can measure frequency and phase difference with figures that twist and turn, yet I'm not a dancer. What am I?

Lissajous figure
