College Assignment About Oscilloscope


This is my undergraduate assignment that I translated to English myself in the Electrical Measurement course where the task is to write an essay on Oscilloscopes. This assignment has never been published anywhere and I, as the author and copyright holder, license this assignment customized CC-BY-SA where anyone can share, copy, republish, and sell on condition to state my name as the author and notify that the original and open version available here.

Chapter 1 Introduction

1.1 Background

Have you ever seen a line drawing that goes up and down, up and down again? Have you ever heard of signals, waves, vibrations, alternating current (AC)? Maybe on television you have seen the form of a signal displayed by news or educational media. Maybe you don't know the measuring instrument that can display the wave image. The measuring instrument is called an oscilloscope.

1.3 Scope of Material

Chapter 2 Basic Theory

2.1 Vibration

The vibrations can be in the form of up and down, left-right, left side - right side, back and forth. In life we feel vibrations are a continuous back and forth motion, for example earthquakes.

Movement of the pendulum from a to c back again to a or a > b > c > b > a is said to be 1 vibration.
Movement of the pendulum from a to c back again to a or a > b > c > b > a is said to be 1 vibration.

2.2 Frequency

Frequency is defined as the number of vibrations that are carried out every second. The unit of frequency in the International System is hertz, abbreviated as Hz. This name is taken from the last name from the figure of Physics, whose name is Heinrich Hertz.

hertz = vibration/second, frequency = vibration/time

2.3 Period

Period is the time it takes to perform 1 vibration.

f swing takes 1 second,

2f swing takes 2 seconds,

100f swing takes 100 seconds,

f/2 swings take 1/2 second,

f/100 swings take 1/100 of a second,

f/f=1 swing, takes 1/f second,

T = 1/f

2.4 Wave

Waves are described as vibrations up and down.
Waves are described as vibrations up and down.

Chapter 3 Discussion

3.1 What is an oscilloscope?

An oscilloscope is an electronic device that can provide an image on the screen (display) of the electrical signal connected to its input. Oscilloscopes usually have an input signal gate and an output signal. Oscilloscopes generally display images in 2 dimensions, the screen is in boxes. There are also 3 dimensions. A wave is converted into electricity, after which it can be read on an oscilloscope. With an oscilloscope it is possible to see the shape of the wave equation of an electrical signal.

3.2 How is the basic circuit of an oscilloscope?

4.1 Conclusion

An oscilloscope is a device that displays electrical signals in the form of waves. Oscilloscopes are used in various fields. Provided that something can be defined in the form of waves.
