Question

By making use of a cro _________



a.Many characteristics of a signal can be measured



b.Only a few characteristics of a signal can be measured



c.No characteristics of a signal can be measured



d.Signal can only be displayed

Answer 1

Answer:

A

Explanation:

Through the means of a Cathode Ray Oscilloscope, most of the characteristics of an input signal can be measured. Properties of a signal can be studied as well.

Answer 2

Cathode Ray Oscilloscope (CRO)

By making use of CRO, MANY CHARACTERISTICS OF A SIGNAL CAN BE MEASURED

KEY TAKEAWAYS OF CATHODE RAY OSCILLOSCOPE:

* An oscilloscope is a piece of electrical equipment that shows the voltage waveform. The Cathode Ray Oscilloscope (CRO) is the most basic oscilloscope, and it shows a time-varying signal or waveform.

* A Cathode Ray Oscilloscope (CRO) is made up of many blocks. Vertical amplifier, delay line, trigger circuit, time base generator, horizontal amplifier, Cathode Ray Tube (CRT), and power supply are the components that make up the vertical amplifier.

* On its screen, CRO shows the voltage signal as a function of time. The amplitude of the voltage signal remains constant, but by adjusting the volt/division knob on the CRO panel, we may change the number of divisions that cover the voltage signal in the vertical direction. As a result, we'll receive the signal's amplitude, which is displayed on CRO's screen.
