UNIT 1: ENGINEERING - WHAT'S IT ALL ABOUT?
1. What is engineering?
Engineering is a scientific field and job that involves taking out scientific understanding of the natural world and using it to invent, design and building things to solve problems and achieve practical goals
Engineering is the application of science and math to solve problems Engineers figure out how things work and find practical uses for scientific discoveries Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world

UNIT : TEST AND REPAIR INSTRUMENTS
Task 1: list as many instruments used for testing and repair in electronics as you can Task 2: how many of these instruments can you identify? Can you explain these use?
Task 3: check your answers to task and by reading this task
(16)16 Multimeter:
This instrument can be use to measure a number of different electrical quantities, such as voltage, current, and resistance, it is a combined voltmeter, ammeter, and ohmmeter Multimeters can have analogue or digital displays and can be switched to different measuring ranges
Multimeter
instrument measure
Logic probe
This instrument is use for measuring voltage levels and pulses in digital logic circuits When the probe is placed on the pin of a logic IC, small coloured leds light up to indicate if a pulse is detected or whether the pin is at a high or a low logic level
Logic probe
Oscilloscope
This instrument is use to measure fast-moving signals It shows how a signal varies with time or relative to another signal It uses a cathode ray tube to display the wareform of the measured signal on a screen
Oscilloscope
(17)17
Function generator
This instrument contains a triangular wave oscillator which can be switched to produce triangular, square, or sine waves over a range of frequences It is use to test and a adjust a variety of electronic equipment such as audio amplifiers The function generator provides a know signal which can be injected into a circuit Often it is used with an oscilloscope so that a visual display of the waveform can be seen
Task 4: which of the instruments would you use to the following?
1.to check a fuse
2 to determine the frequency response of an audio amplifier
3 to test for presence of a control signal on the output pin of a computer chip To determine the value of the current through a transformer
5 to measure the frequency of an oscillator
(18)18 Cathode ray tube
Televisions as well as computers, radar systems, and oscilloscopes use a cathode ray tube(CRT) to produce an output display The construction and operation of the CRT is similar in it case but the simplest type of CRT is found in oscilloscopes
Televisions
A CRT is really a large vacuum tube valve It has main sections The first sections is an electron which emits a stream of electrons The electron gun contains an electron lens which the electrons into a narrow electron
The second section is a system, which allows the beam to be moved or horizontally Oscilloscopes use charged metal to give deflection, where as televiton sets use electromagnetic coils to give electromagnetic
(19)19 Language study: cause and effect,
Study these statements:
1 The electron beam hits the screen
2. The phosphor glows
Why does the phosphor glow? What is the relationship between statement(1) and (2) Statement (1) is a cause and statement(2) is an effect We can link scause and effect statements in a number of ways Study these ways, which use cause and make
1. The electron beam hits the screen causing The phosphor to glow
2 The electron beam hits the screen making The phosphor glow
Now study these cause and effect statements:
3 The phosphor glows
4 A spot is displayed
The effect is in the passive We can link cause and effect like this: The phosphor glows causing a spot to be displayed
Task 6: link each of these cause and effect statements to make one sentence 1.a a magnetic field is set up in the speaker coil
